CVE-2026-3888: Snap Local Privilege Escalation to Root via Public PoC
- Engineer — Plan: Public PoC exists for this snapd LPE flaw, but EPSS is 0.00 and it is not KEV-listed, so no active exploitation pressure yet. Patch snapd to the fixed version on any Ubuntu/Linux hosts where it is installed.
- SOC/IR — Plan: With a public PoC in circulation, this local privilege escalation is a realistic post-initial-access technique; build or tune a detection for unexpected snapd process spawning elevated children mapped to ATT&CK T1068 on Linux endpoints.
- Leader — Skip
- Signals: CVE-2026-3888 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub
