CVE-2026-54229

Abrt: chownproblemdir succeeds during active post-create event processing due to inadequate locking

State: Published
Severity: 7.0 High
Published: Jun 13, 2026

Reserved: Jun 12, 2026

Description

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.
