CVE-2026-98868 dm-pcache: reject a kset that overruns its segment

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: reject a kset that overruns its segment cachereplay, the writeback worker and the GC worker read a kset of getksetonmediasize bytes and advance the position by it. A forged keynum makes that size exceed the segment's...

CVE-2026-98868

A vulnerability exists in the Linux kernel 's dm-pcache component where cache_replay() , the writeback worker, and the GC worker could be misled by a forged key_num . This causes the system to read a kset larger than the segment's remaining space, leading to an out-of-bounds memory access that tr...

CVE-2026-98866

The Linux kernel contains a use-after-free (UAF) vulnerability related to the sched/cache subsystem. The issue occurs when account_mm_sched() attempts to reach a cache group through a task whose mm_struct is currently being switched. To resolve this, a new sched_cache_grp pointer was introduced t...
