CWE-264Published: June 21, 2012· Updated: Jun 16, 2026
2.1
CVSS v3.1
Official Description
The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier does not properly drop group privileges when the -runas option is used, which allows local guest users to access restricted files on the host.
Technical Analysis
CVE-2011-2527 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.
