{"id":"AZL-94950","summary":"CVE-2026-68161 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: close UDP tunnel sockets during netns teardown\n\nproc_sctp_do_udp_port() starts per-net SCTP UDP tunneling sockets when\nnet.sctp.udp_port is set, and stops/restarts them when the sysctl value\nchanges. The netns exit path does not stop these sockets, so a namespace\ncan be torn down while its SCTP UDP tunnel sockets are still installed.\n\nClose the UDP tunnel sockets from sctp_ctrlsock_exit() after unregistering\nthe per-net sysctl table. This prevents new sysctl writes from racing in\nwhile the sockets are being released, and closes the sockets before the\ncontrol socket is destroyed.","modified":"2026-08-31T05:26:27Z","published":"2026-08-10T13:20:02Z","upstream":["CVE-2026-68161"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68161"}],"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-94950.json"}}],"schema_version":"1.9.0"}
