CVE-2026-80959

CVE-2026-80959 affects the Linux kernel's dm-pcache (device-mapper persistent cache) component. The root cause is in cache_pos_decode() , which uses persisted key_tail and dirty_tail seg_off values to address data within a cache segment. A seg_off at or past the segment data_size , controllable b...
