**Name of the Vulnerable Software and Affected Versions** QEMU (affected versions not specified) **Description** A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU. This issue occurs while processing controller commands due to a DMA reentry issue. The flaw allows a guest user or process to consume CPU cycles or crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
