CVE-2026-89757

CVE-2026-89757 affects the Linux kernel 's multi-gen LRU (mglru) subsystem. The root cause is a buggy shortcut in sort_folio() for handling unevictable folios: it fails to initialize mlock_count , causing it to alias LIST_POISON2 (value 290). As a result, __munlock_folio() cannot clear the PG_mlo...
