There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Rekor is a software supply chain transparency log. In versions 1.4.3 and below, the entry implementation
    can panic on attacker-controlled input when canonicalizing a proposed entry with an empty spec.message,
    causing nil Pointer Dereference. Function validate() returns nil (success) when message is empty, leaving
    sign1Msg uninitialized, and Canonicalize() later dereferences v.sign1Msg.Payload. A malformed proposed
    entry of the cose/v0.0.1 type can cause a panic on a thread within the Rekor process. The thread is
    recovered so the client receives a 500 error message and service still continues, so the availability
    impact of this is minimal. This issue has been fixed in version 1.5.0. (CVE-2026-23831)

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-de52e7caa1 advisory.
