CVE-2026-110330
Abrt: abrt: abrt-server trusts client-supplied pid= allowing unprivileged read of other processes' /proc environ
- Medium 5.5
Description
A flaw was found in abrt. abrt-server trusts a client-supplied PID when creating problem dumps over abrt.socket and, running as root, copies that process's /proc data (including environ) into a dump directory owned by the connecting unprivileged user. This allows a local attacker to read environment variables and related metadata of other users' or root processes when abrtd is running.
