CVE-2026-80960

A flaw was found in the Linux kernel's dm-pcache component. A local attacker with CAPSYSADMIN capabilities can exploit this vulnerability by supplying a specially crafted cache device. The segnum value, which dictates the size of cache segments, is not adequately validated against the actual devi...

CVE-2026-80960

CVE-2026-80960 is an out-of-bounds write vulnerability in the Linux kernel's dm-pcache (device-mapper persistent cache) module. The on-media seg_num field, read from a crc32c-only superblock, is attacker-controlled by anyone with CAP_SYS_ADMIN who supplies the cache device at table load. It is ne...
