This avoids deadlock.\n\ndma-fence_ops::signaled can be called with the fence lock in unknown\nstate. For radeon, the fence lock is also the wait queue lock. This can\ncause a self deadlock when signaled() tries to make forward progress on\nthe wait queue. But advancing the queue is unneeded because incorrectly\nreturning false from signaled() is perfectly acceptable.\n\n(cherry picked from commit 527ba26e50ec2ca2be9c7c82f3ad42998a75d0db)","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":["CWE-667"],"references":["https://git.kernel.org/stable/c/73bc12d6a547f9571ce4393acfd73c004e2df9e5","https://git.kernel.org/stable/c/7e3e9b3a44c23c8eac86a41308c05077d6d30f41","https://git.kernel.org/stable/c/9d0ed508a9e2af82951ce7d834f58c139fc2bd9b","https://git.kernel.org/stable/c/9eb00b5f5697bd56baa3222c7a1426fa15bacfb5","https://git.kernel.org/stable/c/d40a72d7e3bad4dfb311ef078f5a57362f088c7f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68223","score":0.00116,"percentile":0.01611,"date":"2026-10-25"},"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).
