CVE-2026-61897 (GCVE-0-2026-61897)

Vulnerability from cvelistv5 – Published: 2026-08-20 14:32 – Updated: 2026-08-20 14:32

Title

accountsservice: incomplete privilege drop when running Ubuntu-specific language helper scripts

Summary

An Ubuntu-specific patch to AccountsService before 23.13.9-8ubuntu7 only partially drops privileges before launching language helper scripts. It changes the effective UID/GID to the target user but leaves the real UID as 0 (root). A shell spawned by a helper script inherits ruid=0 and may reset its effective UID to root, enabling local privilege escalation.

Severity

7.8 (High)
