CVE-2024-26885 – bpf: Fix DEVMAP_HASH overflow check on 32-bit arches
https://notcve.org/view.php?id=CVE-2024-26885
17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf: Fix DEVMAP_HASH overflow check on 32-bit arches The devmap code allocates a number hash buckets equal to the next power of two of the max_entries value provided when creating the map. When rounding up to the next power of two, the 32-bit variable storing the number of buckets can overflow, and the code checks for overflow by checking if the truncated 32-bit value is equal to 0. However, on 32-bit arches the rounding up itself can overf... • https://git.kernel.org/stable/c/6f9d451ab1a33728adb72d7ff66a7b374d665176 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2024-26884 – bpf: Fix hashtab overflow check on 32-bit arches

17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf: Fix hashtab overflow check on 32-bit arches The hashtab code relies on roundup_pow_of_two() to compute the number of hash buckets, and contains an overflow check by checking if the resulting value is 0. However, on 32-bit arches, the roundup code itself can overflow by doing a 32-bit left-shift of an unsigned long value, which is undefined behaviour, so it is not guaranteed to truncate neatly.

17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: dm: call the resume method on internal suspend There is this reported crash when experimenting with the lvm2 testsuite. The list corruption is caused by the fact that the postsuspend and resume methods were not paired correctly; there were two consecutive calls to the origin_postsuspend function.
