Always\nput the reference to the nvmem device as the last step before returning\nthe error code.","modified":"2026-07-08T08:09:45.808899205Z","published":"2026-06-25T08:38:39.495Z","related":["CGA-922h-5rrh-pvr3"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53156.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/40e2a459c0dd1333b2343831480a0ad80dc07614"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b6b6fc491899d583eaa75344e094796ae9b530b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb85ef5a227b3662b88f4d849a1aad43bfe7f5ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0d38bf47a72da2f02c9fa6f752cd66d977cd7f7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53156.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53156"},{"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":"e888d445ac33a5b0288d670ecd970908b13f07cd"},{"fixed":"e0d38bf47a72da2f02c9fa6f752cd66d977cd7f7"},{"fixed":"cb85ef5a227b3662b88f4d849a1aad43bfe7f5ae"},{"fixed":"40e2a459c0dd1333b2343831480a0ad80dc07614"},{"fixed":"5b6b6fc491899d583eaa75344e094796ae9b530b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53156.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"6.12.94"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53156.json"}}],"schema_version":"1.7.5"}
