CVE-2024-42306

The CVE-2024-42306 entry describes a Linux kernel issue in the udf filesystem where a corrupted block bitmap could cause mixed allocation results after a failure, due to bitmap state not being consistently re-validated. The fix uses BH_verified to indicate bitmap validity, preventing reuse of a p...

CVE-2024-42305

CVE-2024-42305 affects the Linux kernel ext4, where a dir-indexing edge case could trigger out-of-bounds access during directory entry splitting when the first two entries are not dot/dotdot. The description and connected material explain that make_indexed_dir() assumed the first two dirents are ...

CVE-2024-42297

CVE-2024-42297 affects the Linux kernel’s f2fs filesystem. The root cause is a path that dirties an inode (FI_DIRTY_INODE) during operations on a read‑only filesystem, leading to a kernel panic in f2fs_evict_inode when unmounting. The provided details trace the sequence from do_sys_open → f2fs_lo...
