The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - amd-pstate: Fix memory leak in amd_pstate_epp_cpu_init() On failure to set the epp, the function     amd_pstate_epp_cpu_init() returns with an error code without freeing the cpudata object that was allocated     at the beginning of the function. Ensure that the cpudata object is freed before returning from the     function. This memory leak was discovered by Claude Opus 4.6 with the aid of Chris Mason's AI review-     prompts (https://github.com/masoncl/review-prompts/tree/main/kernel). (CVE-2026-53121)

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