CVE-2015-4106
CWE-863Published: June 3, 2015· Updated: Jun 17, 2026
4.6
CVSS v3.1
Official Description
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
Technical Analysis
CVE-2015-4106 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
