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.","published":"2026-05-28T10:16:31.000Z","lastModified":"2026-10-19T20:18:35.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-362","CWE-1058"],"affected":["linux/linux kernel"],"epss":{"score":0.00168,"percentile":0.05999,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
