{"id":"AZL-109239","summary":"CVE-2026-98699 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: fix mesh fast xmit path deletion UAF\n\nmesh_fast_tx_cache() stores raw mesh_path pointers. Path deletion\nflushes the cache and then frees the path with kfree_rcu(), but a\nlookup that already holds the path can insert a new cache entry\nafter the flush. The cache then points at freed memory.\n\nSet MESH_PATH_DELETED before flushing, and skip inserting a cache\nentry if the path or MPP path is already deleted. Check this under\nthe cache walk lock so it is ordered with the flush. Use WRITE_ONCE()\nfor the deletion flag updates because the cache check reads flags\nwithout taking state_lock.","modified":"2026-10-19T14:17:06.063731151Z","published":"2026-10-18T16:17:23Z","upstream":["CVE-2026-98699"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98699"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-109239.json"}}],"schema_version":"1.9.0"}
