{"id":"CVE-2023-52593","summary":"wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap()\n\nSince 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()'\nshould check the return value before examining skb data. So convert\nthe latter to return an appropriate error code and propagate it to\nreturn from 'wfx_start_ap()' as well. Compile tested only.","modified":"2026-04-02T09:43:04.401790Z","published":"2024-03-06T06:45:24.551Z","related":["SUSE-SU-2024:1644-1","SUSE-SU-2024:1659-1","SUSE-SU-2024:1663-1","USN-6818-2","USN-6819-2"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52593.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3739121443f5114c6bcf6d841a5124deb006b878"},{"type":"WEB","url":"https://git.kernel.org/stable/c/574dcd3126aa2eed75437137843f254b1190dd03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ab224744a47363f74ea29c6894c405e3bcf5132"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe0a7776d4d19e613bb8dd80fe2d78ae49e8b49d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52593.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52593"},{"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":"268bceec1684932e194ae87877dcc73f534d921c"},{"fixed":"574dcd3126aa2eed75437137843f254b1190dd03"},{"fixed":"9ab224744a47363f74ea29c6894c405e3bcf5132"},{"fixed":"3739121443f5114c6bcf6d841a5124deb006b878"},{"fixed":"fe0a7776d4d19e613bb8dd80fe2d78ae49e8b49d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-52593.json"}}],"schema_version":"1.7.5"}
