Linux Distros Unpatched Vulnerability : CVE-2026-80958

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - dm-pcache: clamp the tail kset read to the segment data region The tail-kset read in cachereplay, the writeback worker and the GC worker bounds its length by...

CVE-2026-80957

A flaw was found in the dm-pcache component of the Linux kernel. A local attacker could exploit a vulnerability in the cachereplay function, which does not properly handle a forged last-kset chain. By crafting a malicious chain that points back to an already visited segment, an attacker can cause...

CVE-2026-80958

CVE-2026-80958 is a buffer over-read in the Linux kernel's dm-pcache (Device Mapper Persistent Cache) component. The tail-kset read performed by cache_replay(), the writeback worker, and the garbage collection (GC) worker incorrectly bounds its length by PCACHE_SEG_SIZE - seg_off (the raw segment...
