**Name of the Vulnerable Software and Affected Versions** QEMU versions prior to 2.5.1 **Description** The issue allows local guest OS administrators to cause a denial of service, resulting in an infinite loop and QEMU process crash. This is achieved by providing crafted values for the `PSTART` and `PSTOP` registers, which are involved in ring buffer control. **Recommendations** For versions prior to 2.5.1, update to version 2.5.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the NE2000 NIC emulation support to minimize the risk of exploitation.
