AnalysisAIv1 – Jul 26, 2026

Local information disclosure in accountsservice on Red Hat Enterprise Linux allows systemd-homed users to read arbitrary files via the SetIconFile handler. A proof-of-concept exists, but exploitation requires a local account managed by systemd-homed, limiting impact

DescriptionCVE.org

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.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
