{"id":"AZL-102519","summary":"CVE-2026-90343 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: stop PMSR before P2P and NAN teardown\n\nPMSR request teardown must abort active measurements while the\nwireless_dev is still present in the driver. cfg80211_leave_locked() and\ncfg80211_stop_pd() already do this before invoking the driver's stop\ncallback, but cfg80211_stop_p2p_device() and cfg80211_stop_nan() do not.\n\nThose helpers are also called directly by nl80211, rfkill shutdown, and\nwireless_dev unregister paths. If one of these paths stops a P2P device\nor NAN interface with a pending request, it removes the mac80211\nsubinterface from the driver first. Subsequent request cleanup cannot\nreach the lower driver's abort callback, but cfg80211 frees the request\nregardless. Driver state can then retain a stale request and use it when\nit later reports a result.\n\nCall cfg80211_pmsr_wdev_down() before stopping the P2P device or NAN\ninterface. This keeps lower-driver request state and cfg80211 request\nownership in sync for all of the helpers' callers.","modified":"2026-09-18T14:17:50.397178984Z","published":"2026-09-17T17:17:32Z","upstream":["CVE-2026-90343"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90343"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102519.json"}}],"schema_version":"1.9.0"}
