This prevents the device from ever\nentering runtime suspend.\n\nAdd the missing pm_runtime_put() before returning on lock failure.","modified":"2026-07-21T03:47:50.627678031Z","published":"2026-07-19T15:40:56.071Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64171.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/57cf4e8d6a57dc2ef5810f4852a23ba4c71b74bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8f7ed203b39004c02479a9156089d87d1ac2c1d8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64171.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64171"},{"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":"6077cfd716fbd4d1f2a3702e49ae8bf65c072685"},{"fixed":"8f7ed203b39004c02479a9156089d87d1ac2c1d8"},{"fixed":"57cf4e8d6a57dc2ef5810f4852a23ba4c71b74bb"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64171.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64171.json"}}],"schema_version":"1.7.5"}
