24 Jan 2023 — A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network subcomponent in the Linux kernel. This flaw causes the system to crash. It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the KVM VMX imp... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cb3e9864cdbe35ff6378966660edbcbac955fe17 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-47929
17 Jan 2023 — In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c. A NULL pointer dereference flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux kernel.

17 Jan 2023 — A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information. Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. • https://github.com/torvalds/linux/commit/ec4eb8a86ade4d22633e1da2a7d85a846b7d1798 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •
