{"id":"CVE-2025-39957","summary":"wifi: mac80211: increase scan_ies_len for S1G","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: increase scan_ies_len for S1G\n\nCurrently the S1G capability element is not taken into account\nfor the scan_ies_len, which leads to a buffer length validation\nfailure in ieee80211_prep_hw_scan() and subsequent WARN in\n__ieee80211_start_scan(). This prevents hw scanning from functioning.\nTo fix ensure we accommodate for the S1G capability length.","modified":"2026-03-20T12:43:06.892119Z","published":"2025-10-09T09:47:34.933Z","related":["MGASA-2025-0309","MGASA-2025-0310","SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4301-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39957.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0dbad5f5549e54ac269cc04ce89f212892a98cab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/32adb020b0c32939da1322dcc87fc0ae2bc935d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e2f3213e85eba00acb4cfe6d71647892d63c3a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93e063f15e17acb8cd6ac90c8f0802c2624e1a74"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39957.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-39957"},{"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":"0333a81bc83431d7f90391d38aa09e856c5e5b25"},{"fixed":"93e063f15e17acb8cd6ac90c8f0802c2624e1a74"},{"fixed":"32adb020b0c32939da1322dcc87fc0ae2bc935d1"},{"fixed":"0dbad5f5549e54ac269cc04ce89f212892a98cab"},{"fixed":"7e2f3213e85eba00acb4cfe6d71647892d63c3a1"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-39957.json"}}],"schema_version":"1.7.5"}
