CVE-2022-48425 – Ubuntu Security Notice USN-6339-3
https://notcve.org/view.php?id=CVE-2022-48425
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.

CVE-2023-28466 – kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference
https://notcve.org/view.php?id=CVE-2023-28466
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 •

03 Mar 2023 — A bug affects the Linux kernel’s ksmbd NTLMv2 authentication and is known to crash the OS immediately in Linux-based systems. 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.

CVE-2022-3707 – kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed
https://notcve.org/view.php?id=CVE-2022-3707
03 Mar 2023 — A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could allow a local user to crash the system. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. • https://bugzilla.redhat.com/show_bug.cgi?id=2137979 • CWE-415: Double Free CWE-460: Improper Cleanup on Thrown Exception •
CVE-2023-1118 – kernel: use-after-free in drivers/media/rc/ene_ir.c due to race condition

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 •
CVE-2023-23005
https://notcve.org/view.php?id=CVE-2023-23005
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 •
CVE-2023-23004 – Ubuntu Security Notice USN-6300-1
https://notcve.org/view.php?id=CVE-2023-23004
01 Mar 2023 — In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer). Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service.

CVE-2023-1095 – kernel: netfilter: NULL pointer dereference in nf_tables due to zeroed list head
https://notcve.org/view.php?id=CVE-2023-1095
28 Feb 2023 — In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference. A NULL pointer dereference flaw was found in the Linux kernel’s netfilter subsystem. The issue could occur due to an error in nf_tables_updtable while freeing a transaction object not placed on the list head. This flaw allow... • https://bugzilla.redhat.com/show_bug.cgi?id=2173973 • CWE-476: NULL Pointer Dereference •
