CVE-2026-93782

The Linux kernel contains a vulnerability in vhost-scsi where the software translates guest response descriptors into userspace iovecs during command submission. Because Target-core completes these commands asynchronously, a VHOST_SET_MEM_TABLE operation can replace the memory table while an in-f...

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...
