This prevents hw scanning from functioning.\nTo fix ensure we accommodate for the S1G capability length.","state":0,"publishedAt":"2025-10-09T09:47:34.933+00:00","modifiedAt":"2026-10-15T22:02:33.942+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"net/mac80211/main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"0333a81bc83431d7f90391d38aa09e856c5e5b25\",\n                            \"lessThan\": \"93e063f15e17acb8cd6ac90c8f0802c2624e1a74\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"0333a81bc83431d7f90391d38aa09e856c5e5b25\",\n                            \"lessThan\": \"32adb020b0c32939da1322dcc87fc0ae2bc935d1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"0333a81bc83431d7f90391d38aa09e856c5e5b25\",\n                            \"lessThan\": \"0dbad5f5549e54ac269cc04ce89f212892a98cab\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"0333a81bc83431d7f90391d38aa09e856c5e5b25\",\n                            \"lessThan\": \"7e2f3213e85eba00acb4cfe6d71647892d63c3a1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"net/mac80211/main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.4\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.6.108\",\n                            \"lessThanOrEqual\": \"6.6.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.49\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.16.9\",\n                            \"lessThanOrEqual\": \"6.16.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.17\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/93e063f15e17acb8cd6ac90c8f0802c2624e1a74","https://git.kernel.org/stable/c/32adb020b0c32939da1322dcc87fc0ae2bc935d1","https://git.kernel.org/stable/c/0dbad5f5549e54ac269cc04ce89f212892a98cab","https://git.kernel.org/stable/c/7e2f3213e85eba00acb4cfe6d71647892d63c3a1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-39957","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-39957","identifiers":["CVE-2025-39957"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
