CVE-2026-93781 scsi: core: Do not block on tag allocation in scsi_eh_lock_door()

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Do not block on tag allocation in scsiehlockdoor scsiehlockdoor is called from scsirestartoperations while the host is still in the SHOSTRECOVERY state, i.e. before the host is switched back to SHOSTRUNNING and...

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...
