{"id":"AZL-68202","summary":"CVE-2025-11234 affecting package qemu for versions less than 6.2.0-25","details":"A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication.","modified":"2026-04-01T05:21:22.358535Z","published":"2025-10-03T11:15:30Z","upstream":["CVE-2025-11234"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-11234"}],"affected":[{"package":{"name":"qemu","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/qemu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-25"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-68202.json"}}],"schema_version":"1.7.5"}
