CVE-2026-74723

A flaw was found in the Linux kernel. A local attacker could craft a btrfs image with a malformed LZO compressed file extent. This could lead to an out-of-bounds read during decompression, potentially causing a denial of service...

CVE-2026-74722

A flaw was found in the Linux kernel's btrfs filesystem. A local attacker could exploit a memory leak in the btrfsdoencodedwrite function. This occurs because an extent changeset is not properly freed before the function returns. Successful exploitation of this memory leak could lead to a denial ...

FFS - F Dateisystem Dies ist ein CLI-Tool zum Durchsuchen von Dateien wie grep, das nicht den OS-Kernel zum Lesen von Dateien verwendet, sondern deine Festplatten direkt liest. Es ist praktisch nutzlos, aber wahnsinnig cool. Das sind nur 1,5k Zeilen C-Code, die: benötigt sudo nur beim Lesen eines...

CVE-2026-74723

A slab-out-of-bounds read in the Linux kernel's btrfs LZO decompression path is triggered when a crafted btrfs image contains an inline LZO compressed file extent with only an LZO header but no segment header or payload. The lzo_decompress() function reads beyond the item boundary; if the extent ...

CVE-2026-74722

This is a memory leak in the btrfs filesystem of the Linux kernel , specifically in the btrfs_do_encoded_write() function. The leak occurs because an extent changeset (allocated via qgroup_reserve_data()) is not freed before the function returns. The bug was discovered through local fuzzing of ke...
