Linux Distros Unpatched Vulnerability : CVE-2026-45022

high Nessus Plugin ID 317320

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.

- go-git is an extensible git implementation library written in pure Go. Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git's decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git's commit signing and verification logic operates over commit data reconstructed from go-git's parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte- for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed.
This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3. (CVE-2026-45022)

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

Solution

There is no known solution at this time.
