CMDQ driver uses devm_mbox_controller_register() in cmdq_probe()\n   to bind the cmdq device to the mbox_controller, so\n   devm_mbox_controller_unregister() will automatically unregister\n   the device bound to the mailbox controller when the device-managed\n   resource is removed. That means devm_mbox_controller_unregister()\n   and cmdq_mbox_shoutdown() will be called after cmdq_remove().\n2. CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after\n   devm_mbox_controller_register(), so that devm_pm_runtime_disable()\n   will be called after cmdq_remove(), but before\n   devm_mbox_controller_unregister().\n\nTo fix this problem, cmdq_probe() needs to move\ndevm_mbox_controller_register() after devm_pm_runtime_enable() to make\ndevm_pm_runtime_disable() be called after\ndevm_mbox_controller_unregister()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/mailbox/mtk-cmdq-mailbox.c"],"versions":[{"version":"623a6143a845bd485b00ba684f0ccef11835edab","lessThan":"1403991a40b94438a2acc749bf05c117abdb34f9","status":"affected","versionType":"git"},{"version":"623a6143a845bd485b00ba684f0ccef11835edab","lessThan":"d00df6700ad10974a7e20646956f4ff22cdbe0ec","status":"affected","versionType":"git"},{"version":"623a6143a845bd485b00ba684f0ccef11835edab","lessThan":"11fa625b45faf0649118b9deaf2d31c86ac41911","status":"affected","versionType":"git"},{"version":"623a6143a845bd485b00ba684f0ccef11835edab","lessThan":"a8bd68e4329f9a0ad1b878733e0f80be6a971649","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/mailbox/mtk-cmdq-mailbox.c"],"versions":[{"version":"4.19","status":"affected"},{"version":"0","lessThan":"4.19","status":"unaffected","versionType":"semver"},{"version":"6.1.120","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.64","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.3","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.1.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.6.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.10.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1403991a40b94438a2acc749bf05c117abdb34f9"},{"url":"https://git.kernel.org/stable/c/d00df6700ad10974a7e20646956f4ff22cdbe0ec"},{"url":"https://git.kernel.org/stable/c/11fa625b45faf0649118b9deaf2d31c86ac41911"},{"url":"https://git.kernel.org/stable/c/a8bd68e4329f9a0ad1b878733e0f80be6a971649"}],"title":"mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-42319","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:09:32.477080Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-12T17:33:26.095Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T20:38:39.733Z"}}]}}
