Vulnerability from cvelistv5 – Published: 2026-07-24 12:56 – Updated: 2026-07-24 13:37

Title

Accountsservice: accountsservice: arbitrary file read via seticonfile for systemd-homed users

Summary

A flaw was found in accountsservice. The systemd-homed code path for SetIconFile opens a user-supplied filename as root without the validation and privilege drop performed by the classic handler. A local attacker with a systemd-homed-managed account can read arbitrary files accessible to the accounts-daemon process.

Severity

5.5 (Medium)
