This can occur when\nzero-length frames (such as WNM NULL frames) are dropped to prevent\npotential hardware TX hangs.\n\nFix this by properly releasing the skb with ieee80211_tx_status_ext()\nwhen tx_prepare_skb() fails.","modified":"2026-09-18T14:16:35.511429765Z","published":"2026-09-17T17:17:37Z","upstream":["CVE-2026-90378"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90378"}],"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-102897.json"}}],"schema_version":"1.9.0"}
