CVSS v3.1 |
| league/commonmark versions >= 2.0.0 and < 2.8.4 (patched in 2.9.0) contain a denial of service vulnerability in UniqueSlugNormalizer::normalize(), which restarts its numeric-suffix search from 1 on every slug collision, resulting in O(K^2) time complexity for K headings that collapse to the same base slug. The vulnerable path is reached when HeadingPermalinkExtension, FootnoteExtension, or TableOfContentsExtension is registered. An unauthenticated attacker can force many headings onto a single base slug (e.g., via empty ATX headings, identical heading text, or punctuation-only headings) in a small Markdown document, consuming excessive CPU and denying service. |
| The league/commonmark (thephpleague/commonmark) library in versions >= 1.5.0 and < 2.9.1 contains quadratic parsing complexity in its SmartPunctExtension and AttributesExtension. When either extension is explicitly registered on the Environment (they are not enabled by default and are excluded from the standard CommonMark and GitHub-Flavored Markdown converters), an unauthenticated attacker can submit small, specially crafted Markdown documents — such as text alternating with unpaired quotes, contiguous runs of block-level attribute blocks, or repeated class attributes — to trigger disproportionate CPU consumption and cause a denial of service. Fixed in 2.9.1. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes
The IIO core does not filter duplicate writes to the event enable
attribute, so writing the same value twice invokes
write_event_config() twice. Enabling twice leaks a runtime PM
reference, preventing the device from ever suspending again;
disabling twice underflows the usage count and triggers a
"Runtime PM usage count underflow" warning.
Bail out early when the requested state matches the current state.
While at it, switch to pm_runtime_resume_and_get() so a failed
resume is propagated to userspace instead of silently marking the
event enabled. |
| In the Linux kernel, the following vulnerability has been resolved:
hugetlbfs: release subpool on fill_super failure
hugetlbfs_fill_super() allocates a hugepage subpool when size or min_size
mount options are specified. hugepage_new_subpool() may also reserve huge
pages for min_size.
If root dentry creation fails after the subpool is created, the failure
path frees the subpool with kfree(). This bypasses hugepage_put_subpool()
and can leave min_size reservations charged.
Use hugepage_put_subpool() on the failure path, matching the normal
put_super path. |
| In the Linux kernel, the following vulnerability has been resolved:
media: bcm2835-unicam: Fix asc leaked in error/remove path
v4l2_async_nf_add_fwnode_remote() allocates the asc, which is freed when
v4l2_async_nf_cleanup() is called.
Call v4l2_async_nf_cleanup() properly in the driver paths.
Discovered with kmemleak after rmmod:

| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix leak in ath11k_service_ready_ext_event()
Currently, during ath11k_service_ready_ext_event() processing,
svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a
temporary allocation that is freed on the success path, but not on the
error path. If parsing succeeds far enough to allocate mac_phy_caps and
then fails on a later TLV, the allocation leaks. So free the allocation
on the error path.
Compile tested only. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt792x: Fix memory leak in SDIO TX path
When tx_prepare_skb() returns an error in the SDIO TX path, the
skb is not freed, leading to a memory leak. This can occur when
zero-length frames (such as WNM NULL frames) are dropped to prevent
potential hardware TX hangs.
Fix this by properly releasing the skb with ieee80211_tx_status_ext()
when tx_prepare_skb() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix infinite loop in nilfs_clean_segments()
syzbot reported a hung task in nilfs_transaction_begin(). This occurs
because the cleaner ioctl falls into an infinite loop if
nilfs_segctor_construct() repeatedly returns -EROFS (e.g. the device
is remounted as read-only after an I/O error).
Currently in nilfs_clean_segments(), if err is non-zero, it logs the
error and sleeps but doesn't abort when it encounters a terminal error
like -EROFS. This causes the thread to loop forever.
Fix this by breaking out of the loop if nilfs_segctor_construct()
returns -EROFS. This matches the behaviour in
nilfs_segctor_write_out(), which also handles -EROFS. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: ad525x_dpot: use driver core groups for sysfs files
ad_dpot_probe() creates per-RDAC sysfs files manually and then
optionally creates the command sysfs group. This leaves probe responsible
for rolling back partial sysfs state and makes remove responsible for
matching every file that probe created.
Move the device attributes into driver core dev_groups for the I2C and
SPI drivers and use an is_visible() callback to expose only the
attributes supported by the probed device. With this shape, the driver
core creates the sysfs files only after probe succeeds and removes them
before the remove callback frees the driver data. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_dp: Release core resources
Core resources such as the DisplayPort AUX channel get initialized and
registered during dw_dp_bind(), but are never unregistered, which may
lead to memory leaks and/or use-after-free:

Since a previous commit exported dw_dp_unbind() function in DW DP core
library to take care of the necessary cleanup, use this in the
component's unbind() callback, as well as in its bind() error path. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()
ipu7_resume() calls pm_runtime_get_sync() before resuming the device.
If the runtime PM resume fails, the usage count remains incremented, but
the error path returns without dropping the reference.
Use pm_runtime_resume_and_get() instead, which balances the usage count
on failure and avoids the leak. Keep returning 0 on error, as resume
callbacks should not propagate failures to the PM core, matching the
behaviour of the ipu6 driver. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gdsc: tear down per-domain genpds in gdsc_unregister()
gdsc_unregister() removes the OF provider entry and tears down the
parent/subdomain wiring, but never calls pm_genpd_remove() on the
individual generic_pm_domain structures registered by gdsc_init():
void gdsc_unregister(struct gdsc_desc *desc)
{
struct device *dev = desc->dev;
size_t num = desc->num;
gdsc_pm_subdomain_remove(desc, num);
of_genpd_del_provider(dev->of_node);
}
That leaves dangling entries on the global gpd_list. After a provider
unbind/rebind cycle (deferred-probe replay during early boot, real
module unload of a clk driver that owns GDSCs, or an OF-overlay tear-
down) the next gdsc_init() will end up trying to re-register a name
that is still in the list and pm_genpd_init() returns -EEXIST.
While we are here, flip the order so the consumer-facing OF provider
entry is the first thing removed -- otherwise a fresh
of_genpd_get_from_provider() call racing with the teardown could
attach to a domain that is mid-removal.
Iterate the scs[] array and pm_genpd_remove() each registered domain
after the subdomain links are torn down. The regulators stay devm-
managed (devm_regulator_get_optional() in gdsc_register()), so the
release happens automatically when the underlying device is unbound;
just the genpd accounting needs to be undone explicitly. |
| A vulnerability was found in O-RAN-SC SMO OAM 2025-06-10. Affected by this vulnerability is an unknown functionality of the component VES Collector. Performing a manipulation results in allocation of resources. The attack may be initiated remotely. The exploit has been made public and could be used. The project was informed of the problem early through a bug report but has not responded yet. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Free transport channel on IDR failure
If transport channel setup succeeds but the following IDR insertion fails,
the error path destroys the transport device and frees the channel info
without invoking the transport cleanup callback.
Call chan_free() before destroying the device so transport specific
resources such as IRQs, mailbox channels and mapped shared memory are
released consistently with the normal teardown path. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Free RX data on late probe failure
hfi1_init_dd() allocates the shared AIP/VNIC RX support before returning.
If hfi1_init() or hfi1_register_ib_device() later fails, init_one() tears
down the device data without calling hfi1_free_rx(). This leaks netdev_rx
and its dummy netdev.
Free the RX support after IB unregistration and before postinit_cleanup(),
as done on normal device removal. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom_q6v5_adsp: Fix reference leak for device node
When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In adsp_map_carveout, it does not release the reference. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Drop handle on protocol bind failures
The SCMI bus notifier acquires an SCMI handle when the driver core emits
BUS_NOTIFY_BIND_DRIVER, before invoking the protocol driver probe
callback. The protocol probe path only checks whether sdev->handle is
set.
If device_link_add() fails after the handle has been acquired, the
protocol device can still bind with a valid handle but without the
dependency link to the SCMI parent. A concurrent parent unbind can then
miss the child and tear down the SCMI instance while the child still
holds a handle into it.
If the protocol driver probe later fails, for example with
-EPROBE_DEFER, the driver core emits BUS_NOTIFY_DRIVER_NOT_BOUND rather
than BUS_NOTIFY_UNBOUND_DRIVER. The SCMI notifier only released the
handle on BUS_NOTIFY_UNBOUND_DRIVER, so each failed protocol-device bind
leaked the SCMI instance users refcount and left sdev->handle set after
the failed probe.
Make the link helper report failure and drop the acquired handle if the
link cannot be created. Also handle BUS_NOTIFY_DRIVER_NOT_BOUND in the
same cleanup path used for unbind so failed probes balance the earlier
BUS_NOTIFY_BIND_DRIVER acquisition. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: free STAG index when TPT entry write fails
write_tpt_entry() allocates a new STAG index with c4iw_get_resource() and
bumps stats.stag.cur before programming the entry. When
write_adapter_mem() fails, it returns the error without releasing the index
or reversing the statistic. No MR is inserted into rhp->mrs, so
deregistration never reclaims it, leaking the index until device teardown.
Record whether this call allocated the index and, on a failed write, return
it to tpt_table and decrement stats.stag.cur. Key the rollback on both the
write error and that flag, not the error alone: a non-reset update carries
a caller-owned STAG that this call did not allocate and must not free. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dsi: Drop dev_pm_opp_set_rate(0)
dev_pm_opp_set_rate(0) removes the vote specified in required-opps but
does not actually park the clock, making it run without the necessary
power backing. Drop the explicit call to it.
Every call site of ops->link_clk_disable() is followed by
pm_runtime_put(), so the power vote will be rescinded if deemed safe.
Patchwork: https://patchwork.freedesktop.org/patch/742783/ |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt76x02: do not WARN on invalid rx descriptor length
The MPDU length in the rx descriptor comes from the hardware. In
monitor mode with the fcsfail filter enabled, the hardware passes up
corrupted frames, and a corrupted frame can report a length larger
than the received buffer. The bounds check correctly discards such
frames, but its WARN_ON_ONCE wrapper means any over-the-air garbage
frame taints the kernel, and panics it on the first such frame when
panic_on_warn is set.
Drop the WARN and discard the frame silently, matching what
commit c2d4c8723dbf ("mt76x2: remove some harmless WARN_ONs in tx
status and rx path") did for the neighboring rx and tx status paths.
Observed immediately on rx with an MT7612U in fcsfail monitor mode
on a busy channel. |
