Linux Distros Unpatched Vulnerability : CVE-2026-1489

medium Nessus Plugin ID 296897

Language:

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 flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable. (CVE-2026-1489)

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

Solution

There is no known solution at this time.
