Linux Distros Unpatched Vulnerability : CVE-2026-54228

high Nessus Plugin ID 320971

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - A time-of-check time-of-use (TOCTOU) race condition was found in the abrt-dbus D-Bus service's SetElement method. Between dump directory creation and post-create event execution, any local user can call SetElement to write arbitrary text files into the root-owned dump directory, bypassing package validation and allowing crashes of unpackaged binaries to survive post-create processing. (CVE-2026-54228)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
