Capture the permission at event-initialization time by storing it\nin event-\u003ehw.flags, and have the NMI handler rely on that cached flag\ninstead of making the call directly.","modified":"2026-06-26T12:06:23.451196505Z","published":"2026-06-24T16:30:46.662Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53114.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0584e74fa2b27e9e722cfb5b579f79263df20040"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2783ed2442ce69ae240b787aee6dae801cef7aec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0a09142622a994c4f4088c3f61db5da87cfc711"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53114.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53114"},{"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":"50a53b60e141d7e31368a87e222e4dd5597bd4ae"},{"fixed":"2783ed2442ce69ae240b787aee6dae801cef7aec"},{"fixed":"0584e74fa2b27e9e722cfb5b579f79263df20040"},{"fixed":"b0a09142622a994c4f4088c3f61db5da87cfc711"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53114.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53114.json"}}],"schema_version":"1.7.5"}
