{"id":"CVE-2026-46152","summary":"wifi: mac80211: drop stray 'static' from fast-RX rx_result","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: drop stray 'static' from fast-RX rx_result\n\nieee80211_invoke_fast_rx() is documented as safe for parallel RX, but\nits per-invocation rx_result is declared static. Concurrent callers then\nshare one instance and can overwrite each other's result between\nieee80211_rx_mesh_data() and the switch on res.\n\nThat can make a packet that was queued or consumed by\nieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make\na packet that should continue return as queued.\n\nMake res an automatic variable so each invocation keeps its own result.","modified":"2026-06-23T15:29:20.909361128Z","published":"2026-05-28T09:36:08.211Z","related":["ALSA-2026:26427","ALSA-2026:26428","ALSA-2026:27789","openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46152.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03584528bfffb195e384698af9148b94e42e3f14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1739fc31b4de06c5c78ce0741182770fb079091e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ef44f96ccc3e06e059dec57842e366f0c4b1893"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a5b81e0c87a075afd572f659d8eb68c9c4cd2ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e131562d6f2b958148c35c98831b007f47f0e3d3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46152.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46152"},{"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":"3468e1e0c639032a603450f0830ccabfa76f5806"},{"fixed":"03584528bfffb195e384698af9148b94e42e3f14"},{"fixed":"1739fc31b4de06c5c78ce0741182770fb079091e"},{"fixed":"e131562d6f2b958148c35c98831b007f47f0e3d3"},{"fixed":"3ef44f96ccc3e06e059dec57842e366f0c4b1893"},{"fixed":"7a5b81e0c87a075afd572f659d8eb68c9c4cd2ba"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46152.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.4.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46152.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
