CVE-2026-98867

The Linux kernel is affected by a vulnerability in dm-pcache where the cache_key_decode() function fails to properly validate the logical offset of a key from persistent memory. An offset exceeding the device size allows the creation of a subtree pointer outside the req_key_tree->subtrees[] ar...

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...

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...

CVE-2026-98865

The Linux kernel contains a vulnerability in the sched_ext component where ops.dequeue() is incorrectly invoked while the source user DSQ lock is still held during the consume and move paths (specifically in scx_consume_dispatch_q() and move_task_between_dsqs()). This flaw can cause a self-deadlo...

CVE-2026-98864

The Linux kernel contains a vulnerability in sched_ext where a task can be found on a DSQ while still in the SCX_OPSS_DISPATCHING state. This occurs because reenqueue paths do not wait for the state to clear in ops_dequeue(), unlike the dequeue and core-sched pick paths. If a reenqueue occurs in ...
