19 Mar 2023 — In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs. Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel contained a race condition during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC driver in the Linux kernel did not proper... • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=467333af2f7b95eeaa61a5b5369a80063cd971fd • CWE-763: Release of Invalid Pointer or Reference •

15 Mar 2023 — do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference). A use-after-free flaw was found in the do_tls_getsockopt function in net/tls/tls_main.c in the Transport Layer Security (TLS) in the Network subcompact in the Linux kernel. This flaw allows an attacker to cause a NULL pointer dereference problem due to a race condition. It was discovered that the Traffic-Control Index imp... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=49c47cc21b5b7a3d8deb18fc57b0aa2ab1286962 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •

02 Mar 2023 — A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. A use-after-free flaw was found in the Linux kernel's integrated infrared receiver/transceiver driver. This issue occurs when a user detaches a rc device. This could allow a local user to crash the system or potentially escalate their privileges on the system. • https://github.com/torvalds/linux/commit/29b0589a865b6f66d141d79b2dd1373e4e50fe17 • CWE-416: Use After Free •

01 Mar 2023 — In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 • CWE-476: NULL Pointer Dereference •

23 Feb 2023 — There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket ... • https://github.com/hshivhare67/kernel_v4.19.72_CVE-2023-0461 • CWE-416: Use After Free •

06 Feb 2023 — A memory leak flaw and potential divide by zero and Integer overflow was found in the Linux kernel V4L2 and vivid test code functionality. This issue occurs when a user triggers ioctls, such as VIDIOC_S_DV_TIMINGS ioctl. This could allow a local user to crash the system if vivid test code enabled. • https://bugzilla.redhat.com/show_bug.cgi?id=2166287 • CWE-20: Improper Input Validation CWE-190: Integer Overflow or Wraparound CWE-369: Divide By Zero CWE-401: Missing Release of Memory after Effective Lifetime •

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.
