CVE-2024-49903

CVE-2024-49903 is a Linux kernel vulnerability involving a slab-use-after-free in the JFS mapping code (dbFreeBits/dbFreeDmap) caused by a race between two paths (dbUnmount and jfs_ioc_trim) that access bmap. The race can lead to uaf when trimming or unmounting JFS and subsequently freeing object...

CVE-2024-49902

CVE-2024-49902 in the Linux kernel affects the JFS dmmap path. The root cause is an out-of-bounds condition in dbSplit when dmt_leafidx exceeds the number of leaves per dmap tree; a bounds check was added in dbFindLeaf. Shaggy’s change also extends the sanity check to cover control pages in addit...
