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 •

28 Feb 2023 — In the Linux kernel before 6.1.2, kernel/module/decompress.c misinterprets the module_get_next_page return value (expects it to be NULL in the error case, whereas it is actually an error pointer). It was discovered that the Traffic-Control Index implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-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 •

26 Feb 2023 — In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c, related to __list_del_entry_valid. 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.

https://notcve.org/view.php?id=CVE-2023-0045
23 Feb 2023 — The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to the prctl syscall.
