https://notcve.org/view.php?id=CVE-2023-23003
01 Mar 2023 — In the Linux kernel before 5.16, tools/perf/util/expr.c lacks a check for the hashmap__new return value. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.16 • CWE-252: Unchecked Return Value •
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-2023-0461 – Use-after-free vulnerability in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-0461
28 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 socke... • https://github.com/hshivhare67/kernel_v4.19.72_CVE-2023-0461 • CWE-416: Use After Free •
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 •
