This leaks\na runtime PM usage-counter reference on every such write, after which the\ndevice can no longer autosuspend.\n\nSet the error code and fall through to the existing put instead of\nreturning early.","modified":"2026-07-27T04:03:22.704289105Z","published":"2026-07-25T08:51:58.186Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64503.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/13a91e8631cfeb68e5b7fd6687f194f5a86e83fe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/191fcfeb729ededd8dd2a999c6bf351ddfa0cec7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/223703d6e8bed50b6a0b47e160877909518d94b9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36154171385a8a2444a4b3c6eaa0c5294cb02478"},{"type":"WEB","url":"https://git.kernel.org/stable/c/44a5fd874bb6873bdaec59f722c1d57832fbc9df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6293211d142605bec435229ef0aa3668b8964164"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a93fd69c1ab0854ac4f5b8439c26dfadb25dfd20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eeece4a85ece6f3837c75ef26a9b2bf5a1d0fcfc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64503.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64503"},{"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":"9a9a369d6178dd4e263c49085ce1b37e1e8f63a0"},{"fixed":"a93fd69c1ab0854ac4f5b8439c26dfadb25dfd20"},{"fixed":"eeece4a85ece6f3837c75ef26a9b2bf5a1d0fcfc"},{"fixed":"191fcfeb729ededd8dd2a999c6bf351ddfa0cec7"},{"fixed":"36154171385a8a2444a4b3c6eaa0c5294cb02478"},{"fixed":"223703d6e8bed50b6a0b47e160877909518d94b9"},{"fixed":"6293211d142605bec435229ef0aa3668b8964164"},{"fixed":"13a91e8631cfeb68e5b7fd6687f194f5a86e83fe"},{"fixed":"44a5fd874bb6873bdaec59f722c1d57832fbc9df"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64503.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.9.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64503.json"}}],"schema_version":"1.7.5"}
