CVE-2024-40985 – net/tcp_ao: Don't leak ao_info on error-path
https://notcve.org/view.php?id=CVE-2024-40985
In the Linux kernel, the following vulnerability has been resolved: net/tcp_ao: Don't leak ao_info on error-path It seems I introduced it together with TCP_AO_CMDF_AO_REQUIRED, on version 5 [1] of TCP-AO patches. Quite frustrative that having all these selftests that I've written, running kmemtest & kcov was always in todo.

CVE-2024-40984 – ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."
https://notcve.org/view.php?id=CVE-2024-40984
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine." Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine.""). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. However, it was found that when this situation arises, mapping continues until the boundary's end, but there is still an attempt to read/write the entire length of the map, leading to a NULL pointer deference. • https://git.kernel.org/stable/c/d410ee5109a1633a686a5663c6743a92e1181f9b https://git.kernel.org/stable/c/435ecc978c3d5d0c4e172ec5b956dc1904061d98 https://git.kernel.org/stable/c/ae465109d82f4fb03c5adbe85f2d6a6a3d59124c https://git.kernel.org/stable/c/6eca23100e9030725f69c1babacd58803f29ec8d https://git.kernel.org/stable/c/dc5017c57f5eee80020c73ff8b67ba7f9fd08b1f https://git.kernel.org/stable/c/ddc1f5f124479360a1fd43f73be950781d172239 https://git.kernel.org/stable/c/434c6b924e1f4c219aab2d9e05fe79c5364e37d3 https://git.kernel.org/stable/c/e21a4c9129c72fa54dd00f5ebf71219b4 • CWE-476: NULL Pointer Dereference •
CVE-2024-40983 – tipc: force a dst refcount before doing decryption
https://notcve.org/view.php?id=CVE-2024-40983
In the Linux kernel, the following vulnerability has been resolved: tipc: force a dst refcount before doing decryption As it says in commit 3bc07321ccc2 ("xfrm: Force a dst refcount before entering the xfrm type handlers"): "Crypto requests might return asynchronous. In this case we leave the rcu protected region, so force a refcount on the skb's destination entry before we enter the xfrm type input/output handlers." On TIPC decryption path it has the same problem, and skb_dst_force() should be called before doing decryption to avoid a possible crash.

CVE-2024-40982 – ssb: Fix potential NULL pointer dereference in ssb_device_uevent()
https://notcve.org/view.php?id=CVE-2024-40982
In the Linux kernel, the following vulnerability has been resolved: ssb: Fix potential NULL pointer dereference in ssb_device_uevent() The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attempting to use it. Found by Linux Verification Center (linuxtesting.org) with SVACE. • https://git.kernel.org/stable/c/c5dc2d8eb3981bae261ea7d1060a80868e886813 https://git.kernel.org/stable/c/7d43c8377c6fc846b1812f8df360425c9323dc56 https://git.kernel.org/stable/c/789c17185fb0f39560496c2beab9b57ce1d0cbe7 •
