To resolve this, a new sched_cache_grp pointer was introduced t...

CVE-2026-98866 sched/cache: Introduce task_struct->sched_cache_grp to fix UAF

In the Linux kernel, the following vulnerability has been resolved: sched/cache: Introduce taskstruct-schedcachegrp to fix UAF Add a schedcachegrp pointer to taskstruct so that scheduler code can access the cache group directly via the task, without going through mm-schedcachegrp. This decouples...
