Linux Distros Unpatched Vulnerability : CVE-2026-92824

medium Nessus Plugin ID 369502

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 libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service. (CVE-2026-92824)

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

Solution

There is no known solution at this time.
