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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1170 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    jfs: fix array-index-out-of-bounds read in add_missing_indices (CVE-2025-38204)

    In the Linux kernel, the following vulnerability has been resolved:

    exfat: fix double free in delayed_free (CVE-2025-38206)

    In the Linux kernel, the following vulnerability has been resolved:

    x86/sev: Evict cache lines during SNP memory validation (CVE-2025-38560)

    In the Linux kernel, the following vulnerability has been resolved:

    netlink: avoid infinite retry looping in netlink_unicast() (CVE-2025-38727)

Tenable has extracted the preceding description block directly from the tested product 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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013527 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    jfs: fix array-index-out-of-bounds read in add_missing_indices

    stbl is s8 but it must contain offsets into slot which can go from 0 to     127.

    Added a bound check for that error and return -EIO if the check fails.
    Also make jfs_readdir return with error if add_missing_indices returns     with an error.

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

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