{"id":"CVE-2025-38609","summary":"PM / devfreq: Check governor before using governor-\u003ename","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nPM / devfreq: Check governor before using governor-\u003ename\n\nCommit 96ffcdf239de (\"PM / devfreq: Remove redundant governor_name from\nstruct devfreq\") removes governor_name and uses governor-\u003ename to replace\nit. But devfreq-\u003egovernor may be NULL and directly using\ndevfreq-\u003egovernor-\u003ename may cause null pointer exception. Move the check of\ngovernor to before using governor-\u003ename.","modified":"2026-03-20T12:42:56.848288Z","published":"2025-08-19T17:03:52.542Z","related":["MGASA-2025-0234","MGASA-2025-0235","SUSE-SU-2025:03272-1","SUSE-SU-2025:03290-1","SUSE-SU-2025:03301-1","SUSE-SU-2025:03382-1","SUSE-SU-2025:03602-1","SUSE-SU-2025:03633-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20653-1","SUSE-SU-2025:20669-1","SUSE-SU-2025:20739-1","SUSE-SU-2025:20756-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38609.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2731c68f536fddcb71332db7f8d78c5eb4684c04"},{"type":"WEB","url":"https://git.kernel.org/stable/c/631e101728df2a86b8fb761b49fad9712c651f8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75323a49aa603cf5484a6d74d0d329e86d756e11"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81f50619370045120c133bfdda5b320c8c97d41e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bab7834c03820eb11269bc48f07c3800192460d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5632359dbc44862fc1ed04093c1f57529830261"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f0479e878d4beb45e73c03e574c59f0a23ccd176"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38609.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38609"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"96ffcdf239de6f9970178bb7d643e16fd9e68ab9"},{"fixed":"f0479e878d4beb45e73c03e574c59f0a23ccd176"},{"fixed":"631e101728df2a86b8fb761b49fad9712c651f8a"},{"fixed":"81f50619370045120c133bfdda5b320c8c97d41e"},{"fixed":"d5632359dbc44862fc1ed04093c1f57529830261"},{"fixed":"2731c68f536fddcb71332db7f8d78c5eb4684c04"},{"fixed":"75323a49aa603cf5484a6d74d0d329e86d756e11"},{"fixed":"bab7834c03820eb11269bc48f07c3800192460d2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38609.json"}}],"schema_version":"1.7.5"}
