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.(CVE-2025-11234)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"qemu","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.1.0-92.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["qemu-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-block-curl-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-block-iscsi-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-block-rbd-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-block-ssh-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-debuginfo-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-debugsource-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-guest-agent-4.1.0-92.oe2003sp4.aarch64.rpm","qemu-img-4.1.0-92.oe2003sp4.aarch64.rpm"],"noarch":["qemu-help-4.1.0-92.oe2003sp4.noarch.rpm"],"src":["qemu-4.1.0-92.oe2003sp4.src.rpm"],"x86_64":["qemu-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-block-curl-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-block-iscsi-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-block-rbd-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-block-ssh-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-debuginfo-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-debugsource-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-guest-agent-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-img-4.1.0-92.oe2003sp4.x86_64.rpm","qemu-seabios-4.1.0-92.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1263"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-11234"}],"database_specific":{"severity":"High"}}
