{"id":"CVE-2025-68223","summary":"drm/radeon: delete radeon_fence_process in is_signaled, no deadlock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/radeon: delete radeon_fence_process in is_signaled, no deadlock\n\nDelete the attempt to progress the queue when checking if fence is\nsignaled. 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)","modified":"2026-04-02T13:03:25.003248Z","published":"2025-12-16T13:57:16.764Z","related":["SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:1078-1","SUSE-SU-2026:20207-1","SUSE-SU-2026:20220-1","SUSE-SU-2026:20228-1","openSUSE-SU-2026:20145-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68223.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/73bc12d6a547f9571ce4393acfd73c004e2df9e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e3e9b3a44c23c8eac86a41308c05077d6d30f41"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d0ed508a9e2af82951ce7d834f58c139fc2bd9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9eb00b5f5697bd56baa3222c7a1426fa15bacfb5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d40a72d7e3bad4dfb311ef078f5a57362f088c7f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68223.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68223"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"954605ca3f897ad617123279eb3404a404cce5ab"},{"fixed":"d40a72d7e3bad4dfb311ef078f5a57362f088c7f"},{"fixed":"9d0ed508a9e2af82951ce7d834f58c139fc2bd9b"},{"fixed":"73bc12d6a547f9571ce4393acfd73c004e2df9e5"},{"fixed":"7e3e9b3a44c23c8eac86a41308c05077d6d30f41"},{"fixed":"9eb00b5f5697bd56baa3222c7a1426fa15bacfb5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68223.json"}}],"schema_version":"1.7.5"}
