CVE-2026-46655
virtio-win provides Windows paravirtualized drivers for QEMU and KVM. From mm210 until mm320, the Viosock driver permits a low-privilege local process to submit an IOCTLSELECT request with attacker-controlled VIRTIOVSOCKSELECT.Fdss.fdcount values that overflow the 32-bit sum used by VIOSockSelect...
CVE-2026-46655
The Viosock driver (viosock.sys) in virtio-win (versions mm210 through mm319) is vulnerable to a local privilege escalation in Windows guests running QEMU or KVM. A low-privilege process can submit an IOCTL_SELECT request with crafted VIRTIO_VSOCK_SELECT.Fdss[*].fd_count values that cause an inte...
