A similar issue was fixed before\nin commit 6694482a70e9 (\"drm/msm: Avoid unclocked GMU register access in\n6xx gpu_busy\"): msm_devfreq_init() does call devfreq_suspend_device(), but\nunlike msm_devfreq_suspend(), it doesn't set the df->suspended flag\naccordingly. This means the df->suspended flag does not match the actual\ndevfreq state after initialization and msm_devfreq_get_dev_status() will\nend up accessing GMU registers, causing the crash.\n\nFix this by setting df->suspended correctly during initialization.\n\nPatchwork: https://patchwork.freedesktop.org/patch/650772/"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/msm/msm_gpu_devfreq.c"],"versions":[{"version":"6694482a70e9536efbf2ac233cbf0c302d6e2dae","lessThan":"ae2015b0dbc0eea7aaf022194371f451f784d994","status":"affected","versionType":"git"},{"version":"6694482a70e9536efbf2ac233cbf0c302d6e2dae","lessThan":"7946a10f8da75abc494e4bb80243e153e93e459a","status":"affected","versionType":"git"},{"version":"6694482a70e9536efbf2ac233cbf0c302d6e2dae","lessThan":"1847ea44e3bdf7da8ff4158bc01b43a2e46394bd","status":"affected","versionType":"git"},{"version":"6694482a70e9536efbf2ac233cbf0c302d6e2dae","lessThan":"a6f673cc9488fd722c601fe020601dba14db21b2","status":"affected","versionType":"git"},{"version":"6694482a70e9536efbf2ac233cbf0c302d6e2dae","lessThan":"b71717735be48d7743a34897e9e44a0b53e30c0e","status":"affected","versionType":"git"},{"version":"1f6c087dd6a915f1c3471f0f0f696847fc8c592f","status":"affected","versionType":"git"},{"version":"9c8b3f05fb18fba12f3fca80a378c9b8f3d04cd6","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/gpu/drm/msm/msm_gpu_devfreq.c"],"versions":[{"version":"6.0","status":"affected"},{"version":"0","lessThan":"6.0","status":"unaffected","versionType":"semver"},{"version":"6.1.143","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.96","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.36","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.5","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","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":"6.0","versionEndExcluding":"6.1.143"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.6.96"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.12.36"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.15.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18.18"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ae2015b0dbc0eea7aaf022194371f451f784d994"},{"url":"https://git.kernel.org/stable/c/7946a10f8da75abc494e4bb80243e153e93e459a"},{"url":"https://git.kernel.org/stable/c/1847ea44e3bdf7da8ff4158bc01b43a2e46394bd"},{"url":"https://git.kernel.org/stable/c/a6f673cc9488fd722c601fe020601dba14db21b2"},{"url":"https://git.kernel.org/stable/c/b71717735be48d7743a34897e9e44a0b53e30c0e"}],"title":"drm/msm/gpu: Fix crash when throttling GPU immediately during boot","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T17:37:03.909Z"}}]}}
