CVE-2015-6815
CWE-835Published: January 31, 2020· Updated: Jun 17, 2026
3.5
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2015-6815 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
