CVE-2026-54229 Red Hat CVE debrief

CVE-2026-54229 is a HIGH-severity vulnerability with a CVSS score of 7. The vulnerability is caused by a race condition in the abrt-dbus D-Bus service's ChownProblemDir method. This method 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.
