Last modified
CVE-2015-6815 is a low-severity vulnerability rated 3.5/10 on the CVSS scale. The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors.. EPSS estimates a 0.98% chance of exploitation in the next 30 days.
