The vulnerability of the `virtio_gpu_set_scanout` function in the `hw/display/virtio-gpu.c` component of the QEMU hardware emulation software occurs due to a lack of memory release mechanism before deleting the last reference. This allows a malicious actor to trigger a service failure.

The vulnerability of the virtiogpusetscanout function in the hw/display/virtio-gpu.c component of the QEMU hardware emulation software is related to a lack of a mechanism for freeing memory before deleting the last pointer. Exploiting this vulnerability allows an attacker to trigger a service...

OESA-2021-1227 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fixes: A flaw was found in vhost-user-gpu of QEMU in versions up to and including 6.0. An out-of-bounds write vulnerability can allow a malicious guest to crash the QEMU process on the host...

An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on the host resulting in a denial of service condition or potential code execution with the privileges of the QEMU process.

An information disclosure vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw exists in virgl_cmd_get_capset_info() in contrib/vhost-user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit this issue to leak memory from the host.
