Name of the Vulnerable Software and Affected Versions
QEMU versions prior to 5.0.0
Description
The issue is related to an assertion failure in the network packet processing, affecting the e1000e and vmxnet3 network devices. A malicious guest user or process could exploit this flaw to abort the QEMU process on the host, resulting in a denial of service condition. This occurs in the
net tx pkt add raw fragment function in hw/net/net tx pkt.c.Recommendations
For QEMU versions prior to 5.0.0, update to version 5.0.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the
net tx pkt add raw fragment function in hw/net/net tx pkt.c to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
