A flaw was found in abrt. The completeness check introduced to mitigate CVE-2026-54228 and CVE-2026-54229 only verifies that a dump directory contains a "count" element, which an unprivileged user can create. This allows a local attacker to bypass the guard and again poison elements in, or seize ownership of, dump directories while privileged ABRT handlers are processing them. Related Problems2 mutating methods remain ungated by the same check.

Solution

No solution given by the vendor.


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 abrt installed. Note that abrt-dbus is D-Bus activatable even when abrtd is stopped.
