CVE-2026-3888: CWE-268 Privilege chainingCVE-2026-3888 0 CVE-2026-3888 is a local privilege escalation vulnerability in snapd on Linux systems, specifically affecting multiple Ubuntu LTS versions from 16.04 through 24.04. The flaw arises when systemd-tmpfiles is configured to automatically clean snap's private /tmp directory, allowing a local attacker to re-create this directory and escalate privileges to root. The vulnerability has a high severity score of 7.8, reflecting its potential to compromise confidentiality, integrity, and availability. Exploitation requires local access and elevated privileges but no user interaction. No known exploits are currently reported in the wild. Organizations running affected Ubuntu LTS versions with snapd and systemd-tmpfiles configured as described should prioritize patching or mitigating this issue to prevent privilege chaining attacks.
