CVE-2026-93781

The Linux kernel contains a vulnerability in the scsi_eh_lock_door() function where it may block on tag allocation during the host recovery state (SHOST_RECOVERY ). Specifically, calling scsi_alloc_request() without the BLK_MQ_REQ_NOWAIT flag can cause a circular dependency: the error handler thr...

CVE-2026-93220

The Linux kernel contains a vulnerability in sched_ext where the kick_sync_wait_bal_cb() function incorrectly assumes it always executes on the request queue's (rq ) own CPU. Because the rq lock can be dropped while the callback is queued, it may be executed on a foreign CPU . This leads to compa...
