CVE-2026-16743

EUVD-2026-48570
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.
