Linux Distros Unpatched Vulnerability : CVE-2025-26598

high Nessus Plugin ID 231625

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.

- An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. (CVE-2025-26598)

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

Solution

There is no known solution at this time.
