# CVE-2026-110330: Abrt: abrt: abrt-server trusts client-supplied pid= allowing unprivileged read of other processes' /proc environ

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

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.

## Remediation

- workaround: Disable or remove ABRT if not required: systemctl disable --now abrtd.service abrt-journal-core.service abrt-oops.service abrt-xorg.service. Restrict local interactive user access on systems that keep abrtd enabled. (source: CNA: redhat)
