In the Linux kernel, the following vulnerability has been resolved: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc() syzbot found hanging tasks waiting on rtnl_lock [1] A reproducer is available in the syzbot bug. When a request to add multiple actions with the same index is sent, the second request will block forever on the first request. This holds rtnl_lock, and causes tasks to hang. Return -EAGAIN to prevent infinite looping, while keeping documented behavior. [1] INFO: task kworker/1:0:5088 blocked for more than 143 seconds.

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 •
