{"id":"AZL-106224","summary":"CVE-2026-98233 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/packet: clear RX owner on VNET header error\n\nCommit 61fad6816fc1 (\"net/packet: tpacket_rcv: avoid a producer race\ncondition\") added rx_owner_map and made tpacket_rcv() claim a V1 or V2\nring slot before converting the virtio-net header.  If the conversion\nfails, the drop path leaves the slot claimed.\n\nWith a one-frame TPACKET_V2 ring, an unsupported UDP GSO packet leaves\nthe only slot unavailable, so the ring also drops the next valid packet.\n\nClear the ownership bit on this error path.  TPACKET_V3 already clears\nits block state here.","modified":"2026-10-07T14:16:59.710797842Z","published":"2026-10-06T09:18:10Z","upstream":["CVE-2026-98233"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98233"}],"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-106224.json"}}],"schema_version":"1.9.0"}
