In such cases, the driver\ntries to access AUX channel and causes NULL pointer dereference.\nInitializing the AUX channel earlier to prevent such error.","modified":"2026-03-20T11:47:39.235039Z","published":"2025-12-30T12:11:03.949Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0317-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50847.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/172d4d64075075f955e6e416915e3f287eec514a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8ed8505803774fc3f36a432718036c21cc51e2ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e577d4b13064c337b83fe7edecb3f34e87144821"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50847.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50847"},{"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":"b5c84a9edcd418cd055becad6a22439e7c5e3bf8"},{"fixed":"8ed8505803774fc3f36a432718036c21cc51e2ba"},{"fixed":"172d4d64075075f955e6e416915e3f287eec514a"},{"fixed":"e577d4b13064c337b83fe7edecb3f34e87144821"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50847.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50847.json"}}],"schema_version":"1.7.5"}
