In the Linux kernel, the following vulnerability has been resolved: ext4: Avoid allocating blocks from a group with a corrupted block bitmap in ext4mbtrybestfound. Determine whether the group block bitmap is corrupted before using acbex in ext4mbtrybestfound to prevent allocating blocks from a...

CVE-2026-63796

A flaw was found in the Linux kernel's Oracle Cluster File System 2 ocfs2. A local attacker could craft a malicious group bitmap descriptor that claims a size exceeding the physically allocated bitmap bytes. This improper input validation allows subsequent operations to read or write beyond the...

CVE-2026-63796

CVE-2026-63796 concerns the Linux kernel’s OCFS2 filesystem. The issue arises when a malicious group descriptor can claim a bg_size/bg_bits pair that exceeds the on-disk group bitmap capacity, allowing bitmap scans and bit updates to run past bg_bitmap. The fix adds a physical-capacity check (bas...
