In that\ncase, the call to of_devfreq_cooling_register() will immediately try to\napply devfreq cooling, as seen in the following crash:\n\n  Unable to handle kernel paging request at virtual address 0000000000014110\n  pc : a6xx_gpu_busy+0x1c/0x58 [msm]\n  lr : msm_devfreq_get_dev_status+0xbc/0x140 [msm]\n  Call trace:\n   a6xx_gpu_busy+0x1c/0x58 [msm] (P)\n   devfreq_simple_ondemand_func+0x3c/0x150\n   devfreq_update_target+0x44/0xd8\n   qos_max_notifier_call+0x30/0x84\n   blocking_notifier_call_chain+0x6c/0xa0\n   pm_qos_update_target+0xd0/0x110\n   freq_qos_apply+0x3c/0x74\n   apply_constraint+0x88/0x148\n   __dev_pm_qos_update_request+0x7c/0xcc\n   dev_pm_qos_update_request+0x38/0x5c\n   devfreq_cooling_set_cur_state+0x98/0xf0\n   __thermal_cdev_update+0x64/0xb4\n   thermal_cdev_update+0x4c/0x58\n   step_wise_manage+0x1f0/0x318\n   __thermal_zone_device_update+0x278/0x424\n   __thermal_cooling_device_register+0x2bc/0x308\n   thermal_of_cooling_device_register+0x10/0x1c\n   of_devfreq_cooling_register_power+0x240/0x2bc\n   of_devfreq_cooling_register+0x14/0x20\n   msm_devfreq_init+0xc4/0x1a0 [msm]\n   msm_gpu_init+0x304/0x574 [msm]\n   adreno_gpu_init+0x1c4/0x2e0 [msm]\n   a6xx_gpu_init+0x5c8/0x9c8 [msm]\n   adreno_bind+0x2a8/0x33c [msm]\n   ...\n\nAt this point we haven't initialized the GMU at all yet, so we cannot read\nthe GMU registers inside a6xx_gpu_busy(). 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/","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/1847ea44e3bdf7da8ff4158bc01b43a2e46394bd","https://git.kernel.org/stable/c/7946a10f8da75abc494e4bb80243e153e93e459a","https://git.kernel.org/stable/c/a6f673cc9488fd722c601fe020601dba14db21b2","https://git.kernel.org/stable/c/ae2015b0dbc0eea7aaf022194371f451f784d994","https://git.kernel.org/stable/c/b71717735be48d7743a34897e9e44a0b53e30c0e"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-38354","score":0.00189,"percentile":0.08599,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
