CVE-2025-38230

CVE-2025-38230 concerns the Linux kernel’s JFS subsystem. The issue arises from not validating AG parameters in dbMount(), allowing corrupted metadata to reach dbAllocAG and cause crashes. A UBSAN shift-out-of-bounds occurs in fs/jfs/jfs_dmap.c:1400 during dbAllocAG, as demonstrated by the trace ...

CVE-2025-38230 jfs: validate AG parameters in dbMount() to prevent crashes

CVE-2025-38204

CVE-2025-38204 affects the Linux kernel’s JFS filesystem. The issue is an array-index-out-of-bounds read in add_missing_indices, where stbl (s8) must map to offsets 0–127. A bound check was added and -EIO is returned if the check fails; jfs_readdir is also updated to propagate errors from add_mis...
