Race Condition Vulnerability in abrt-dbus ChownProblemDir Method (CVE-2026-54229)
Summary
A race condition vulnerability (CVE-2026-54229) has been discovered in the abrt-dbus D-Bus service's ChownProblemDir method. The method opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change file ownership to the caller's uid, which can succeed even while post-create event handlers hold a write lock. This flaw enables an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.

· 3 pulledA 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.
