If this cmd times out and\nclearing the doorbell fails, ufshcd_wait_for_dev_cmd() will do nothing and\nreturn. hba->dev_cmd.complete struct is not set to NULL.\n\nWhen this happens, if cmd has been completed by device, then we will call\ncomplete() in __ufshcd_transfer_req_compl(). Because the complete struct is\nallocated on the stack, the following crash will occur:\n\n  ipanic_die+0x24/0x38 [mrdump]\n  die+0x344/0x748\n  arm64_notify_die+0x44/0x104\n  do_debug_exception+0x104/0x1e0\n  el1_dbg+0x38/0x54\n  el1_sync_handler+0x40/0x88\n  el1_sync+0x8c/0x140\n  queued_spin_lock_slowpath+0x2e4/0x3c0\n  __ufshcd_transfer_req_compl+0x3b0/0x1164\n  ufshcd_trc_handler+0x15c/0x308\n  ufshcd_host_reset_and_restore+0x54/0x260\n  ufshcd_reset_and_restore+0x28c/0x57c\n  ufshcd_err_handler+0xeb8/0x1b6c\n  process_one_work+0x288/0x964\n  worker_thread+0x4bc/0xc7c\n  kthread+0x15c/0x264\n  ret_from_fork+0x10/0x30","published":"2025-09-18T14:15:42.000Z","lastModified":"2026-08-04T10:19:05.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["linux/linux kernel"],"epss":{"score":0.00154,"percentile":0.04511,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.15%).
