CVE-2019-15901

27
FAUCET Score

CVE-2019-15901 describes a privilege escalation vulnerability in the doas utility (slicer69 doas before 6.2) on Linux and potentially NetBSD. The flaw arises because a critical setusercontext(3) call was incorrectly replaced with only setuid(2), failing to properly change group IDs. This high-severity vulnerability (CVSS 8.8) allows an authenticated attacker to achieve full compromise (confidentiality, integrity, availability) of the affected system. Despite its severity, there is currently no public exploit code, and it shows minimal community discussion or media coverage, indicating it is not actively exploited.
