The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986769 advisory.

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

    x86/fpu: Prevent state corruption in __fpu__restore_sig()

    The non-compacted slowpath uses __copy_from_user() and copies the entire     user buffer into the kernel buffer, verbatim.  This means that the kernel     buffer may now contain entirely invalid state on which XRSTOR will #GP.
    validate_user_xstate_header() can detect some of that corruption, but that     leaves the onus on callers to clear the buffer.

    Prior to XSAVES support, it was possible just to reinitialize the buffer,     completely, but with supervisor states that is not longer possible as the     buffer clearing code split got it backwards. Fixing that is possible but     not corrupting the state in the first place is more robust.

    Avoid corruption of the kernel XSAVE buffer by using copy_user_to_xstate()     which validates the XSAVE header contents before copying the actual states     to the kernel. copy_user_to_xstate() was previously only called for     compacted-format kernel buffers, but it works for both compacted and     non-compacted forms.

    Using it for the non-compacted form is slower because of multiple
    __copy_from_user() operations, but that cost is less important than robust     code in an already slow path.

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.

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