{"id":"CVE-2026-43052","summary":"wifi: mac80211: check tdls flag in ieee80211_tdls_oper","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: check tdls flag in ieee80211_tdls_oper\n\nWhen NL80211_TDLS_ENABLE_LINK is called, the code only checks if the\nstation exists but not whether it is actually a TDLS station. This\nallows the operation to proceed for non-TDLS stations, causing\nunintended side effects like modifying channel context and HT\nprotection before failing.\n\nAdd a check for sta-\u003esta.tdls early in the ENABLE_LINK case, before\nany side effects occur, to ensure the operation is only allowed for\nactual TDLS peers.","modified":"2026-07-11T03:53:49.764295775Z","published":"2026-05-01T14:15:46.029Z","related":["SUSE-SU-2026:22108-1","SUSE-SU-2026:22137-1","SUSE-SU-2026:22433-1","SUSE-SU-2026:22458-1","SUSE-SU-2026:2450-1","SUSE-SU-2026:2482-1","SUSE-SU-2026:2591-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43052.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44839ea7e96b3659a1606f3d5267063135479b7c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6813a8b1b240756dad4375f3e020ce10e4e3871b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d73872d949c488a1d7c308031d6a9d89b5e0a8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8148c2fda4ebb17104a573649c9b699208ad10ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ba5b43db126a5e7378553869e3f7954d9187349f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be81f17151fcb8546a95f35ca8f4231b065985de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e602246235fc2ef06c39b2e9cf147d84d0896b73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e77b2937aaa20264e4bd699d3244bdb50e7e3343"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43052.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43052"},{"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":"941c93cd039852b7ab02c74f4698c99d82bd6cfe"},{"fixed":"e602246235fc2ef06c39b2e9cf147d84d0896b73"},{"fixed":"6813a8b1b240756dad4375f3e020ce10e4e3871b"},{"fixed":"44839ea7e96b3659a1606f3d5267063135479b7c"},{"fixed":"ba5b43db126a5e7378553869e3f7954d9187349f"},{"fixed":"8148c2fda4ebb17104a573649c9b699208ad10ee"},{"fixed":"be81f17151fcb8546a95f35ca8f4231b065985de"},{"fixed":"e77b2937aaa20264e4bd699d3244bdb50e7e3343"},{"fixed":"7d73872d949c488a1d7c308031d6a9d89b5e0a8b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43052.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.2.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.142"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.81"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43052.json"}}],"schema_version":"1.7.5"}
