Linux Distros Unpatched Vulnerability : CVE-2026-80960

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - dm-pcache: validate on-media segnum against the cache device size segnum is read from the crc32c-only superblock, so whoever supplies the cache device on a tabl...

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...
