CVSS v3.1 |
| The smartphone application "Vehicle Inspection Certificate Viewer" contains a vulnerability in which sensitive information may be included in data transmitted by the application, potentially leading to the exposure of API integration credentials such as an access ID and access key. |
| A vulnerability has been identified in Siemens Software Center (All versions < V4.0.9.8). The affected application loads dynamic-link libraries (DLLs) from an uncontrolled search path. This could allow an authenticated local attacker to place a specially crafted DLL in a directory that the application searches, leading to arbitrary code execution with the privileges of the affected application. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/vfio-ap: fix KVM GISC and page leak when queue removed from host config
Three related problems exist in the handling of KVM interrupt and page
resources when a queue is removed from the host's AP configuration
while assigned to a mediated device (mdev).
Problem 1:
~~~~~~~~~
AP_RESPONSE_Q_NOT_AVAIL not handled in vfio_ap_mdev_reset_queue()
When the AP bus removes a queue device whose adapter or domain has
been removed from the host's AP configuration,
vfio_ap_mdev_remove_queue() is called. If the queue is still in the
host's AP configuration at that point, it calls
vfio_ap_mdev_reset_queue(), which issues a PQAP(ZAPQ). Since the
adapter is already gone from the host configuration, ap_zapq() returns
AP_RESPONSE_Q_NOT_AVAIL (0x01). This response code is not handled in
vfio_ap_mdev_reset_queue()'s switch statement and falls through to
the default case, which issues a WARN but does not call
vfio_ap_free_aqic_resources(). As a result, if IRQ handling was
enabled for the queue by the guest, the KVM GISC registration and
the pinned guest page holding the notification indicator byte (NIB)
are both leaked.
This is fixed by adding AP_RESPONSE_Q_NOT_AVAIL to the same case as
AP_RESPONSE_DECONFIGURED and AP_RESPONSE_CHECKSTOPPED in
vfio_ap_mdev_reset_queue(). Like those response codes, Q_NOT_AVAIL
indicates the queue is not operational and no further reset attempts
are possible; the correct action is to free the IRQ resources
immediately.
Problem 2:
~~~~~~~~~
AP_RESPONSE_Q_NOT_AVAIL not handled in apq_status_check()
In vfio_ap_mdev_reset_queue(), there are four cases that indicate a queue
reset has not yet completed, in which case apq_reset_check() is queued to
a work queue to verify completion of the reset operation. This function
uses the PQAP(TAPQ) function to get the queue's status and calls
apq_status_check() to verify whether the reset has completed, failed or
needs to be executed again. As described in Problem #1 above,
apq_reset_check() does not specifically check for AP_RESPONSE_Q_NOT_AVAIL,
thereby potentially leaking KVM GISC registration and the pinned guest page
holding the NIB.
This is fixed by adding a case statement for AP_RESPONSE_Q_NOT_AVAIL to
apq_status_check() and returning -ENODEV for that case. The caller,
apq_reset_check() will then check for this return code and call
vfio_ap_free_aqic_resources() to prevent the leak.
Problem 3:
~~~~~~~~~
vfio_ap_free_aqic_resources() leaks saved_isc when kvm is NULL
vfio_ap_free_aqic_resources() guards the call to
kvm_s390_gisc_unregister() with:
if (q->saved_isc != VFIO_AP_ISC_INVALID &&
!WARN_ON(!(q->matrix_mdev && q->matrix_mdev->kvm)))
If matrix_mdev->kvm is NULL -- which can happen when
vfio_ap_mdev_unset_kvm() has already run and cleared kvm before a
subsequent cleanup path reaches this function -- the WARN_ON fires
and the entire block is skipped. This leaves q->saved_isc set to a
non-invalid value, creating a potential double-free on any subsequent
call to this function.
When kvm is NULL the KVM guest is already torn down, so
kvm_s390_gisc_unregister() need not and cannot be called; however,
q->saved_isc must always be cleared. Fix this by separating the
kvm_s390_gisc_unregister() call from the q->saved_isc reset. The
WARN_ON now guards only the genuinely impossible case of matrix_mdev
being NULL. A NULL kvm is handled gracefully by skipping only the
unregister call, and q->saved_isc = VFIO_AP_ISC_INVALID is set
unconditionally whenever saved_isc was not already invalid.
Additionally, add an else clause to the host-config check in
vfio_ap_mdev_remove_queue() to call vfio_ap_free_aqic_resources()
directly when the queue is not in the host's AP configuration. This
serves as a backstop: when the AP bus fires the driver .remove
callback after an adapter is removed from the host config, the queue
is by definition no longer addressable, so vfio_ap_mdev_reset_queue

| In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Keep internal commands dispatchable during error handling
Commit 08b12cda6c44 ("scsi: ufs: core: Switch to scsi_get_internal_cmd()")
switched UFS internal commands to allocate requests on
hba->host->pseudo_sdev->request_queue, which shares the host tagset with
regular LUNs.
During error recovery, ufshcd_err_handling_prepare() calls
blk_mq_quiesce_tagset(&hba->host->tag_set), marking all queues in the
tagset as quiesced, including pseudo_sdev->request_queue. When
ufshcd_verify_dev_init() subsequently issues internal commands (e.g. NOP
OUT UPIU) via blk_execute_rq(), blk_mq_run_hw_queue() skips running the
quiesced queue, resulting in an unrecoverable circular wait deadlock.
Keep quiescing the tagset and unquiesce the pseudo SCSI device on top of
that, so internal commands stay dispatchable while the logical units remain
quiesced. Re-quiesce the pseudo device before unquiescing the tagset so
that quiesce_depth stays balanced.
Clock scaling and ufshcd_pause_command_processing() are unaffected: they
keep quiescing the whole tagset, internal commands included. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: drop truncated I/RR/RNR PDUs in nfc_llcp_recv_hdlc()
nfc_llcp_recv_hdlc() reads the sequence byte skb->data[2], via
nfc_llcp_ns()/nfc_llcp_nr(), before any length check. The receive path
only guarantees the two-byte LLCP header -- __nfc_llcp_recv() checks it
with pskb_may_pull() and nfc_llcp_recv_agf() admits two-byte inner PDUs
-- so a two-byte I, RR or RNR PDU reads one byte of uninitialised skb
tailroom. The byte becomes N(R)/N(S); a peer can already set those with
a well-formed PDU, so this is acting on uninitialised memory, not new
peer control.
Guard the read with pskb_may_pull(), as commit 95674f506c63 ("nfc: llcp:
reject PDUs shorter than the LLCP header") did for the two-byte header,
so the sequence byte is present and linear before it is read. RR and RNR
PDUs are LLCP_HEADER_SIZE + LLCP_SEQUENCE_SIZE bytes and an I PDU is
longer, so no valid frame is rejected; a truncated PDU is malformed, so
return without a DM reply. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: fix use-after-free in nfc_get_local_general_bytes
Commit 6709d4b7bc2e ("net: nfc: Fix use-after-free caused by
nfc_llcp_find_local") attempted to fix a use-after-free (UAF) issue by
invoking nfc_llcp_local_put(local) after accessing local->gb. However,
if the reference count drops to zero, local is freed immediately,
leading to a use-after-free when callers access the returned pointer.
Alternative approaches using dynamic allocation (e.g. kmemdup) introduced
memory leaks because callers consistently treat the returned pointer as
borrowed memory.
Fix this properly by refactoring nfc_llcp_general_bytes() and
nfc_get_local_general_bytes() to accept a caller-provided output buffer
(out_gb) and its maximum length (gb_max_len). The general bytes are
safely copied into out_gb before calling nfc_llcp_local_put(local),
ensuring safe lifetime management without ownership transfer complications.
Update all callers across drivers (microread, pn533, pn544, st21nfca,
digital_dep, and nci) to provide their own destination buffers and pass
them to nfc_get_local_general_bytes(). |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: skip expired catchall elements on insert and delete
nft_setelem_catchall_insert() looks up duplicates with
nft_set_elem_active() only, while nft_set_catchall_lookup() and the
dump path additionally skip expired elements.
Once a catchall element with a timeout expires, this predicate drift
makes it invisible to userspace dumps, yet it still blocks
re-insertion: with NLM_F_EXCL the request fails with -EEXIST, and
without it the request reports success but silently inserts nothing.
The stale entry only goes away when the (user-tunable) gc interval
elapses, so the catchall rule may silently stop matching for an
arbitrarily long time after its first expiration.
The delete path shows the same drift: nft_setelem_catchall_deactivate()
picks the first active-next entry in the catchall list, so with an
expired entry still pending GC it retires the stale entry instead of
the fresh one, and it deactivates an element that userspace no longer
sees instead of failing with -ENOENT.
Align both walks with the lookup and dump predicates: only an element
that is active and not expired counts as a duplicate or delete
candidate, using the per-netns timestamp taken at transaction start,
in line with the set backend .insert/.deactivate and catchall GC sync
paths. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mdb: restart port group walk after deletion
br_mdb_flush_pgs() keeps a pointer-to-pointer cursor while walking
mp->ports. br_multicast_del_pg() can re-enter the same MDB entry through
br_multicast_sg_del_exclude_ports() and unlink other port groups. If the
cursor points into one of those groups, the next iteration dereferences a
stale cursor and can leave mp->ports pointing at freed memory.
A following RTM_GETMDB exposes the dangling pointer:
BUG: KASAN: slab-use-after-free in br_mdb_dump
Read of size 8
br_mdb_dump
rtnl_mdb_dump
rtnl_dumpit
netlink_dump
Reset the cursor to mp->ports after every deletion. The deletion removes at
least the selected group, so the restarted walk always makes progress. |
| In the Linux kernel, the following vulnerability has been resolved:
net: atl1e: fix soft lockup on out-of-range hw_next_to_clean read
Same issue as atl1c (see the first commit in this series, "net:
atl1c: fix soft lockup on out-of-range tpd_cons read"): the hardware
can report an out-of-range hw_next_to_clean (seen as 0xffff) while
the PCIe link/MAC is resetting. An out-of-range value can never be
reached and the loop below would spin forever. Treat it as "nothing
new to clean" instead. |

| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix AArch32 DBGBXVR<n> handling
The consolidation of the breakpoint and watchpoint register accessors
switched DBGBXVR<n> from trap_bvr() to trap_dbg_wb_reg(). The latter
selects backing storage with demux_wb_reg(), which only handles Op2 values
4 through 7. Since DBGBXVR<n> uses Op2 1, an AArch32 guest access hits
KVM_BUG_ON() and marks the VM dead.
DBGBXVR<n> aliases DBGBVR<n>_EL1[63:32], and its AA32(HI) descriptor
already selects the upper half. Map Op2 1 to dbg_bvr[] alongside Op2 4,
restoring the pre-regression behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Don't WARN on an unknown VM ioctl in protected mode
kvm_pkvm_ioctl_allowed() WARNs when kvm_get_cap_for_kvm_ioctl() doesn't
find the ioctl number in vm_ioctl_caps[], and kvm_arch_vm_ioctl() calls
it for every number the generic code doesn't handle, so
ioctl(vm_fd, 0xdeadbeef) from userspace taints a pKVM host and panics it
under panic_on_warn. The lookup is fed userspace input: return false,
and userspace gets the -EINVAL kvm_arch_vm_ioctl() returns for that
number on a host without pKVM. |
| In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: conntrack: fix helper UAF due to extensions realloc
While calling the helpers, a raw pointer to the extensions area is
wired into expectations list:
-> nf_ct_helper()
-> helper->help()
-> nf_ct_expect_related_report()
-> nf_ct_expect_insert()
-> hlist_add_head_rcu(&exp->lnode, &master_help->expectations)
In case the connection is not confirmed yet, more extensions can be
added afterwards with *_ext_add() calls reallocating the extension
space and leaving the now invalid pointer in the expectations list
that is later accessed while removing the expectation.
Make sure that helpers are called at the end after all the other
extensions are already added.
Note that the helper rejection now leaves the mark and labels set,
but that's not different from how the NAT was handled before or how
the mark and the labels were handled on confirmation failure. And
there are no atomicity guarantees provided by the API anyway. |
| In the Linux kernel, the following vulnerability has been resolved:
net: macb: fix dma_alloc_coherent() leak on macb_alloc() error paths
Fix 3 leaks in macb_alloc() error paths:
- Tx buffer allocated but crossing a 4G boundary: Tx leaked.
- Rx buffer allocation fails: Tx leaked.
- Rx buffer allocated but crossing a 4G boundary: Tx & Rx leaked.
This is because our error handling calls macb_free(bp) which in turn
frees the buffers stored in bp->queues[0], but nothing has been stored
in there. Fix by storing allocated buffers into bp->queues[0] ASAP. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ipconfig: bound DHCP option construction
ic_dhcp_init_options() appends the hostname (option 12), vendor-class
(option 60) and client-ID (option 61) options into the fixed 312-byte
bootp_pkt.exten[] buffer. Only the client-ID branch checked the
remaining space; the hostname and vendor-class writes were unbounded.
A 64-byte hostname together with the maximum 252-byte dhcpclass=
identifier needs 18 + (2 + 64) + (2 + 252) = 338 of the 312 available
bytes even before the terminating END marker, so the vendor-class memcpy
runs past the end of exten[]. With CONFIG_FORTIFY_SOURCE this is
reported as a field-spanning write and, when the kernel is booted with
panic_on_warn=1, aborts boot with a panic.
Route the optional options through a common helper that makes sure the
option, its 2-byte header and the END marker all fit and drops an option
that would not. Configurations with short options keep sending exactly
the same bytes as before. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: hid-oxp: use cancel_delayed_work_sync() in remove
oxp_hid_remove() uses cancel_delayed_work() for all three delayed work
items. cancel_delayed_work() only dequeues a pending work item without
waiting for a currently executing callback to finish. If any of the
work callbacks (oxp_rgb_queue_fn, oxp_btn_queue_fn, oxp_mcu_init_fn) is
running at the time of removal, the callback continues executing
concurrently with hid_hw_close() and hid_hw_stop(), accessing the HID
device after it has been closed and stopped.
Use cancel_delayed_work_sync() instead to ensure that any in-progress
work callback completes before device teardown proceeds. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel_pcie: validate device-supplied DMA indices
In btintel_pcie_msix_rx_handle(), the driver processes RX completion
descriptors (urbd1) written by the PCIe device into DMA-coherent memory.
urbd1->frbd_tag (a 16-bit field fully controlled by the device firmware
via DMA) is used directly as an array index into rxq->bufs[] without any
bounds check. rxq->bufs[] has only BTINTEL_PCIE_RX_DESCS_COUNT (64)
entries, while frbd_tag can be any value 0-65535. A malicious or
malfunctioning device can write an out-of-range frbd_tag, causing the
driver to dereference an out-of-bounds data_buf pointer.
Additionally, cr_hia is read from a DMA-shared index array also writable
by the device; if the device sets cr_hia >= rxq->count, the while-loop
never terminates because cr_tia is wrapped via modulo rxq->count and can
never equal an out-of-range cr_hia.
Add bounds validation for cr_hia and frbd_tag in the RX path, and cr_hia
in the TX path. Log invalid values with bt_dev_err before returning. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: samsung-dsim: fix TE GPIO lifetime for host attach
When the Exynos DSI driver was generalized into samsung-dsim, the TE
GPIO acquisition was switched from gpiod_get_optional() to
devm_gpiod_get_optional() while keeping the matching gpiod_put() calls.
That combination is wrong for a managed descriptor.
However, dropping the puts and keeping the managed get is also wrong:
samsung_dsim_register_te_irq() runs from the DSI host attach callback,
and host detach/reattach can happen without destroying the device that
owns the managed action. A second attach would then request the GPIO
again without having released it.
Switch back to a non-managed gpiod_get_optional() and keep the explicit
gpiod_put() on the request_irq() error path and in
samsung_dsim_unregister_te_irq().
