This was reported for MacBookPro 12,1 with\nCirrus codec.\n\nAs a workaround, extend for the 9.1 channels and also fix the\npotential Oops by unifying the code paths accessing the same array\nwith the proper size check.","modified":"2026-04-11T12:46:46.220608Z","published":"2025-09-18T13:33:40.338Z","related":["SUSE-SU-2025:03614-1","SUSE-SU-2025:03615-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3761-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53400.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/082dcd51667b29097500c824c37f24da997a6a8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b44ec8c5c44790a82f07e90db45643c762878c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ef155ddf9578bf035964d58739fdcd7dd44b4a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/546b1f5f45a355ae0d3a8041cdaca597dfcac825"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5694aae4c2d9a288bafce7d38f122769e0428e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc8c569d59f17b17d7bca4f68c36bd571659921e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8c7d7c43d5edd20e518fe1dfb2371d1fe6e8bb8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fcf637461019e9a5a0c12fc5c42a9db1779b0634"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53400.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53400"},{"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":"247d85ee068610c50d66ee0cd3130e02c69f5f2e"},{"fixed":"082dcd51667b29097500c824c37f24da997a6a8a"},{"fixed":"b5694aae4c2d9a288bafce7d38f122769e0428e6"},{"fixed":"4ef155ddf9578bf035964d58739fdcd7dd44b4a4"},{"fixed":"546b1f5f45a355ae0d3a8041cdaca597dfcac825"},{"fixed":"e8c7d7c43d5edd20e518fe1dfb2371d1fe6e8bb8"},{"fixed":"dc8c569d59f17b17d7bca4f68c36bd571659921e"},{"fixed":"fcf637461019e9a5a0c12fc5c42a9db1779b0634"},{"fixed":"3b44ec8c5c44790a82f07e90db45643c762878c6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53400.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.9.0"},{"fixed":"4.14.316"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.284"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.244"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.181"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.3.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53400.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
