QEMU Denial of Service Vulnerability (CNVD-2022-84161)

QEMU is a suite of emulation processor software from Fabrice Bellard, a French personal developer. QEMU 6.2.0 and earlier versions contain an information disclosure vulnerability that stems from the fact that invalid elements in vhost-vsock devices are not separated from the virtqueue before releasing memory, which can be exploited by attackers to cause memory leaks and other unexpected results.
