In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: pmf: Use device managed allocations If setting up smart PC fails for any reason then this can lead to a double free when unloading amd-pmf. This is because dev->buf was freed but never set to NULL and is again freed in amd_pmf_remove(). To avoid subtle allocation bugs in failures leading to a double free change all allocations into device managed allocations.

The remote Ubuntu 24.04 LTS / 25.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7834-1 advisory.

    Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Kpf, Stavros Volos, and Flavien Solt discovered     that some AMD processors may allow an attacker to infer data from previous stores, potentially resulting     in the leakage of privileged information. A local attacker could possibly use this to expose sensitive     information. (CVE-2024-36350, CVE-2024-36357)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - platform/x86/amd: pmf: Use device managed allocations If setting up smart PC fails for any reason then     this can lead to a double free when unloading amd-pmf. This is because dev->buf was freed but never set to     NULL and is again freed in amd_pmf_remove(). To avoid subtle allocation bugs in failures leading to a     double free change all allocations into device managed allocations. (CVE-2025-38421)

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