Hence fill them\nduring transmit call for proper usage to avoid NULL pointer dereference.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1","modified":"2026-03-20T12:11:01.994983Z","published":"2025-09-15T14:04:31.143Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53180.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/054b5580a36e435692c203c19abdcb9f7734320e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7382d02160ef93c806fe1c1d4ef1fec445266747"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53180.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53180"},{"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":"d889913205cf7ebda905b1e62c5867ed4e39f6c2"},{"fixed":"7382d02160ef93c806fe1c1d4ef1fec445266747"},{"fixed":"054b5580a36e435692c203c19abdcb9f7734320e"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53180.json"}}],"schema_version":"1.7.5"}
