      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: Keep internal commands dispatchable during error handling\n\nCommit 08b12cda6c44 (\"scsi: ufs: core: Switch to scsi_get_internal_cmd()\")\nswitched UFS internal commands to allocate requests on\nhba->host->pseudo_sdev->request_queue, which shares the host tagset with\nregular LUNs.\n\nDuring error recovery, ufshcd_err_handling_prepare() calls\nblk_mq_quiesce_tagset(&hba->host->tag_set), marking all queues in the\ntagset as quiesced, including pseudo_sdev->request_queue. When\nufshcd_verify_dev_init() subsequently issues internal commands (e.g. NOP\nOUT UPIU) via blk_execute_rq(), blk_mq_run_hw_queue() skips running the\nquiesced queue, resulting in an unrecoverable circular wait deadlock.\n\nKeep quiescing the tagset and unquiesce the pseudo SCSI device on top of\nthat, so internal commands stay dispatchable while the logical units remain\nquiesced. Re-quiesce the pseudo device before unquiescing the tagset so\nthat quiesce_depth stays balanced.\n\nClock scaling and ufshcd_pause_command_processing() are unaffected: they\nkeep quiescing the whole tagset, internal commands included.",
