What is CVE-2026-110330?

A vulnerability in abrt has been identified where the abrt-server accepts a client-supplied Process ID (PID) without proper validation. This flaw allows unprivileged local attackers to access sensitive process data from /proc, including environment variables of other users or root processes, if the abrtd daemon is running. This can potentially lead to unauthorized privilege escalation and exposure of sensitive system information.
