CVE-2019-19520

27
FAUCET Score

CVE-2019-19520 describes a local privilege escalation vulnerability in xlock within OpenBSD 6.6, allowing local users to gain auth group privileges. This high-severity flaw (CVSS 7.8) arises from mishandling of the LIBGL_DRIVERS_PATH environment variable in xenocara/lib/mesa/src/loader/loader.c, leading to potential complete compromise of confidentiality, integrity, and availability. While no public exploits, Metasploit modules, or community discussions are noted, the vulnerability poses a significant risk to affected OpenBSD systems if exploited locally.
