{"id":"AZL-73611","summary":"CVE-2025-38617 affecting package kernel for versions less than 5.15.200.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/packet: fix a race in packet_set_ring() and packet_notifier()\n\nWhen packet_set_ring() releases po-\u003ebind_lock, another thread can\nrun packet_notifier() and process an NETDEV_UP event.\n\nThis race and the fix are both similar to that of commit 15fe076edea7\n(\"net/packet: fix a race in packet_bind() and packet_notifier()\").\n\nThere too the packet_notifier NETDEV_UP event managed to run while a\npo-\u003ebind_lock critical section had to be temporarily released. And\nthe fix was similarly to temporarily set po-\u003enum to zero to keep\nthe socket unhooked until the lock is retaken.\n\nThe po-\u003ebind_lock in packet_set_ring and packet_notifier precede the\nintroduction of git history.","modified":"2026-04-01T05:22:19.211865Z","published":"2025-08-22T14:15:46Z","upstream":["CVE-2025-38617"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38617"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73611.json"}}],"schema_version":"1.7.5"}
