{"id":"AZL-78401","summary":"CVE-2025-68223 affecting package kernel 5.15.200.1-1","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":"2026-04-01T05:23:14.345356Z","published":"2025-12-16T14:15:55Z","upstream":["CVE-2025-68223"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68223"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-78401.json"}}],"schema_version":"1.7.5"}
