CVE-2026-63818

CVE-2026-63818 affects the Linux kernel’s f2fs filesystem. The issue arises when f2fs_recover_orphan_inodes() trusts the orphan block entry_count from the checkpoint pack; a corrupted entry_count larger than F2FS_ORPHANS_PER_BLOCK can cause the recovery loop to read past the inode array, leading ...
