CVE-2026-93588 1 Imagemagick 1 Imagemagick 2026-09-22 3.1 Low
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.
CVE-2026-76192 1 Adobe 1 Indesign Desktop 2026-09-22 5.5 Medium
InDesign Desktop is affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2026-38999 2026-09-22 7.5 High
A Null Pointer Dereference in the mk_sched_event_close function (mk_server/mk_scheduler.c) of Monkey through commit 4fb0c16 allows attackers to cause a Denial of Service (DoS) via sending a crafted HTTP request to the server.
CVE-2026-93312 1 Freedesktop 1 Poppler 2026-09-22 4.3 Medium
A flaw has been found in Freedesktop Poppler 26.07.0. Impacted is the function JBIG2Stream::rewind of the file poppler/JBIG2Stream.cc. This manipulation causes null pointer dereference. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 26.08.0 is recommended to address this issue.

CVE-2026-86056 1 Notepad-plus-plus 1 Notepad++ 2026-09-22 5.5 Medium
Notepad++ is a free and open-source source code editor. Prior to 8.9.8, the NPPM_SAVESESSION handler in PowerEditor/src/NppBigSwitch.cpp converts lParam to a sessionInfo pointer and dereferences its nbFile, files, and sessionFilePathName members without checking for null. A process running at the same or a higher Windows integrity level on the same desktop can send NPPM_SAVESESSION with a null lParam, immediately terminating Notepad++ and causing denial of service and loss of unsaved documents. This issue is fixed in version 8.9.8.

CVE-2026-76781 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-09-21 5.5 Medium
A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS).
CVE-2026-72949 1 Microsoft 11 Windows 11 23h2, Windows 11 23h2, Windows 11 24h2 and 8 more 2026-09-21 7.5 High
Null pointer dereference in Windows SMB Server Network Transport Driver (srvnet.sys) allows an unauthorized attacker to deny service over a network.
CVE-2026-90828 1 Gnu 1 Binutils 2026-09-21 5.3 Medium
A security flaw has been discovered in GNU Binutils 2.47. This vulnerability affects the function elf_orphan_compatible of the file ld/ldelf.c of the component ELF Orphan Section Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.
CVE-2026-85150 2 Freedesktop, Redhat 2 Gstreamer, Enterprise Linux 2026-09-21 7.5 High
A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.
CVE-2026-90430 1 Linux 1 Linux Kernel 2026-09-21 N/A
In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Publish an LVCMDQ only after it is fully initialized tegra241_vintf_init_lvcmdq() stores the freshly allocated vcmdq pointer to the vintf->lvcmdqs[] array, before tegra241_vcmdq_alloc_smmu_cmdq() builds the vcmdq->cmdq. The error ISR dereferences that cmdq, so a latched LVCMDQ error (e.g. one inherited across a kexec) firing in this window would make tegra241_vintf0_handle_error() pass the still-zeroed arm_smmu_cmdq down to __arm_smmu_cmdq_skip_err(), dereferencing NULL queue register pointers. Drop the store from tegra241_vintf_init_lvcmdq() and publish the vcmdq at the end of the allocation instead, with an smp_store_release() that pairs with an smp_load_acquire() in the ISR, which can see a fully built LVCMDQ or NULL. The user-owned LVCMDQ allocation moves accordingly, publishing the vcmdq once tegra241_vcmdq_hw_init_user() succeeds, using a plain store since a user VINTF's lvcmdqs[] has no lockless reader -- the error ISR only walks the VINTF0 array.
CVE-2026-90039 1 Linux 1 Linux Kernel 2026-09-21 N/A
In the Linux kernel, the following vulnerability has been resolved: NFSD: Guard admin state-revocation walks with NFSD_NET_UP Writing to /proc/fs/nfsd/unlock_filesystem, or sending the NFSD_CMD_UNLOCK_FILESYSTEM or NFSD_CMD_UNLOCK_EXPORT netlink command, walks the NFSv4 client hash tables to revoke open state and cancel async COPY operations. All three handlers gate that walk on nn->nfsd_serv, but a listener added via portlist or netlink listener_set sets nn->nfsd_serv before any nfsd thread starts. nfsd_startup_net() has not yet allocated nn->conf_id_hashtbl, so the walkers dereference a NULL table. A local administrator with CAP_SYS_ADMIN can crash the kernel this way without ever starting the server. nn->nfsd_serv is set when the service is created, which precedes table allocation. NFSD_NET_UP instead brackets the window where the tables are live: set at the end of nfsd_startup_net() and cleared in nfsd_shutdown_net() after they are freed, both under nfsd_mutex. Gating the three unlock paths on NFSD_NET_UP fixes the startup-time NULL dereference while preserving the earlier post-shutdown use-after-free fix.
CVE-2026-89798 1 Linux 1 Linux Kernel 2026-09-21 N/A
In the Linux kernel, the following vulnerability has been resolved: rpcrdma: arm rn_done before publishing the notification rpcrdma_rn_register() inserts @rn into rd_xa with xa_alloc() before storing the caller's callback in rn->rn_done. The xarray makes @rn reachable to rpcrdma_remove_one(), which walks rd_xa and invokes rn->rn_done(rn) for every registered notification. A device removal that races a fresh registration can therefore observe @rn with rn_done still NULL, because the notification objects are zero allocated by their owners, and call through a NULL function pointer. Store rn->rn_done before xa_alloc() publishes @rn. The xarray's store-side and load-side ordering then guarantees that any CPU which finds @rn in rd_xa also observes the armed callback. rpcrdma_rn_unregister() treats a non-NULL rn_done as the sentinel for a completed registration, so the early store must not survive a failed registration. Clear rn_done again when xa_alloc() fails. Were it left set, the failed-accept cleanup path would call rpcrdma_rn_unregister() on an @rn that was never inserted, erasing an unrelated rd_xa slot and underflowing rd_kref.
CVE-2026-68337 1 Linux 1 Linux Kernel 2026-09-21 4.1 Medium
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject redirect helpers without a bpf_net_context The bpf_redirect*() helpers and skb_do_redirect() obtain the per-task bpf_redirect_info via bpf_net_ctx_get_ri(), which dereferences the current->bpf_net_context unconditionally. That context is established on the paths that run tc BPF such as sch_handle_{ingress,egress}(), *except* for the case where {cls,act}_bpf was attached to a proper qdisc. A program running from there reaches the NULL deref in two ways: * It calls bpf_redirect() directly, which dereferences the context at the top of the helper: tc qdisc add dev eth0 root handle 1: red limit 1MB min 10KB max 20KB \ avpkt 1000 burst 100 qevent early_drop block 10 tc filter add block 10 pref 1 bpf obj redirect.o * It simply returns TC_ACT_REDIRECT without helper call: tcf_qevent_handle() then dispatches to skb_do_redirect(), which dereferences the context Rather than extending bpf_net_context management into the qdisc path, make the redirect helpers refuse to operate when no context exists, and have tcf_qevent_handle() drop a TC_ACT_REDIRECT verdict instead of calling skb_do_redirect(). Previous behaviour was a crash, so nothing regresses by not supporting it.
CVE-2026-75439 1 Free5gc 1 Upf 2026-09-21 7.5 High
An issue in Free5GC v.4.2.2 allows a remote attacker to cause a denial of service via the UPF component
CVE-2026-79590 1 Mruby 1 Mruby 2026-09-21 6.5 Medium
A NULL pointer dereference vulnerability exists in the Prism parser component of mruby 4.0.0. An attacker can provide a specially crafted Ruby source file that triggers the parser to pass a NULL pointer to nonnull string handling functions, resulting in undefined behavior and application crash.
CVE-2026-65412 1 Apple 6 Ios And Ipados, Ipados, Iphone Os and 3 more 2026-09-20 6.5 Medium

CVE-2026-90080 1 Linux 1 Linux Kernel 2026-09-20 N/A
In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: fix NULL deref of af_xdp_zc_qidx on rep setup af_xdp_zc_qidx tracks receive queues using AF_XDP zero-copy and is allocated during PF/VF probe. Representors and other non-AF_XDP paths leave the pointer NULL, but several call sites used test_bit() on it unconditionally. Switching to devlink eswitch mode creates representors and runs otx2_init_hw_resources(), which reaches otx2_pool_aq_init() and oopses when dereferencing the NULL bitmap. Add NULL checks before every af_xdp_zc_qidx test_bit() use in the RSS, ethtool, XSK, and pool init paths.
