Detailsinfo

A vulnerability has been found in Red Hat Enterprise Linux 6/7/8 and classified as critical. This vulnerability affects some unknown processing of the component abrt-dbus D-Bus Service. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability was named CVE-2026-54229 since 06/12/2026. The exploitation appears to be difficult. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 06/13/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
