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","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/36822124f9de200cedc2f42516301b50d386a6cd","https://git.kernel.org/stable/c/3ffd2cd644e0f1eea01339831bac4b1054e8817c","https://git.kernel.org/stable/c/cf45493432704786a0f8294c7723ad4eeb5fff24"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2023-53387","score":0.00154,"percentile":0.04535,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
