CVE-2022-49710 – dm mirror log: round up region bitmap size to BITS_PER_LONG
https://notcve.org/view.php?id=CVE-2022-49710
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: dm mirror log: round up region bitmap size to BITS_PER_LONG The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan. • https://git.kernel.org/stable/c/29121bd0b00ebb9524971a583fea4a2f7afe8041 •

It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserv... • https://git.kernel.org/stable/c/0dc2fca8e4f9ac4a40e8424a10163369cca0cc06 •

CVE-2022-49700 – mm/slub: add missing TID updates on slab deactivation
https://notcve.org/view.php?id=CVE-2022-49700
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mm/slub: add missing TID updates on slab deactivation The fastpath in slab_alloc_node() assumes that c->slab is stable as long as the TID stays the same. However, two places in __slab_alloc() currently don't update the TID when deactivating the CPU slab. If multiple operations race the right way, this could lead to an object getting lost; or, in an even more unlikely situation, it could even lead to an object being freed onto the wrong slab... • https://git.kernel.org/stable/c/03e404af26dc2ea0d278d7a342de0aab394793ce •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: dm raid: fix accesses beyond end of raid member array On dm-raid table load (using raid_ctr), dm-raid allocates an array rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks is defined by the number of raid metadata and image tupples passed into the target's constructor.
