The routine\nexits when sa_ctl is NULL and fcport is allocated after the exit call thus\ncausing NULL fcport pointer to dereference at the time of exit.\n\nTo avoid fcport pointer dereference, exit the routine when sa_ctl is NULL.","modified":"2026-04-02T09:44:35.764684Z","published":"2025-10-04T15:44:13.820Z","related":["SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4111-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4139-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4149-1","SUSE-SU-2025:4189-1","SUSE-SU-2025:4301-1","SUSE-SU-2025:4320-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53603.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4406fe8a96a946c7ea5724ee59625755a1d9c59d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/477bc74ad1add644b606bff6ba1284943c42818a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6b504d06976fe4a61cc05dedc68b84fadb397f77"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bbeff613ec0560fb2f6f8b405288f3f043adf64"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53603.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53603"},{"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":"7b2fbfa4b2cd3a24c1760b85d842e928070d4744"},{"fixed":"4406fe8a96a946c7ea5724ee59625755a1d9c59d"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e0fb8ce2bb9e52c846e54ad2c58b5b7beb13eb09"},{"fixed":"477bc74ad1add644b606bff6ba1284943c42818a"},{"fixed":"7bbeff613ec0560fb2f6f8b405288f3f043adf64"},{"fixed":"6b504d06976fe4a61cc05dedc68b84fadb397f77"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"47b583ad1f7e459689eb1bdd222279a6986ccd69"},{"last_affected":"d2deafaef0330a863b5e046c1154b605588d19f7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53603.json"}}],"schema_version":"1.7.5"}
