The query path holds dev_lock and then calls\npm_runtime_resume_and_get(), which waits for the ongoing suspend to\ncomplete. Meanwhile, the suspend callback attempts to acquire dev_lock\nand blocks, resulting in a deadlock.\n\nFix this by releasing dev_lock before calling pm_runtime_resume_and_get()\nand reacquiring it after the call completes. Also acquire dev_lock in the\nresume callback to keep the locking consistent.\n\n## Affected\n\n- `linux_kernel >= 6.19, < 6.19.7`\n- `linux_kernel = 7.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.19.7`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":222250,"id":"CVE-2026-23295","ts":1792065859463,"field":"cvss","old":null,"new":"5.5"},{"seq":222249,"id":"CVE-2026-23295","ts":1792065859463,"field":"severity","old":"none","new":"medium"}]}
