{"id":"AZL-100880","summary":"CVE-2026-80987 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nNTB: ntb_transport: Reject oversized TX buffers\n\nntb_process_tx() handles an oversized buffer by calling tx_handler()\nwith a NULL data pointer and returning success. ntb_netdev therefore\nneither frees the skb in its completion callback nor takes its enqueue\nerror path, leaking it.\n\nReject oversized buffers in ntb_transport_tx_enqueue() before acquiring\na queue entry and return -EMSGSIZE. The caller retains ownership of the\nbuffer, and the preceding netdev patch frees the skb when enqueue\nreturns this permanent error.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:05Z","upstream":["CVE-2026-80987"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80987"}],"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-100880.json"}}],"schema_version":"1.9.0"}
