{"id":"AZL-110924","summary":"CVE-2026-99045 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nibmveth: h_free logical LAN on open-fail after register\n\nibmveth_open() registers the logical LAN, then allocates the RX\nbuffer pools. A pool failure jumps to out_free_buffer_pools without\nh_free_logical_lan(), so PHYP still owns the buffer-list page when\nit is unmapped. request_irq() failure already issued the hypercall\nbefore taking the same label.\n\nMove that h_free to the shared post-register unwind so both paths\nderegister before the buffer list is unmapped.","modified":"2026-10-25T05:30:37Z","published":"2026-10-23T13:17:27Z","upstream":["CVE-2026-99045"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99045"}],"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-110924.json"}}],"schema_version":"1.9.0"}
