Improper handling of insufficient entropy in the AMD CPUs could allow a local attacker to influence the values returned by the RDSEED instruction, potentially resulting in the consumption of insufficiently random values.

The remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8475-1 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)

    It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle     entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could     possibly use this issue to influence the values returned by the RDSEED instruction causing loss of     confidentiality and integrity. (CVE-2025-62626)

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 remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8094-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container. (LP: #2143853)

A local attacker could     possibly use this issue to influence the values returned by the RDSEED instruction causing loss of     confidentiality and integrity. (CVE-2025-62626)
