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

  - bpf: Fix wrong reg type conversion in release_reference() Some helper functions will allocate memory. To     avoid memory leaks, the verifier requires the eBPF program to release these memories by calling the     corresponding helper functions. When a resource is released, all pointer registers corresponding to the     resource should be invalidated. The verifier use release_references() to do this job, by apply
    __mark_reg_unknown() to each relevant register. It will give these registers the type of SCALAR_VALUE. A     register that will contain a pointer value at runtime, but of type SCALAR_VALUE, which may allow the     unprivileged user to get a kernel pointer by storing this register into a map. Using __mark_reg_not_init()     while NOT allow_ptr_leaks can mitigate this problem. (CVE-2022-49873)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989391 advisory.

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986761 advisory.

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

    bpf: Fix wrong reg type conversion in release_reference()

    Some helper functions will allocate memory. To avoid memory leaks, the     verifier requires the eBPF program to release these memories by calling     the corresponding helper functions.

    When a resource is released, all pointer registers corresponding to the     resource should be invalidated. The verifier use release_references() to     do this job, by apply  __mark_reg_unknown() to each relevant register.

    It will give these registers the type of SCALAR_VALUE. A register that     will contain a pointer value at runtime, but of type SCALAR_VALUE, which     may allow the unprivileged user to get a kernel pointer by storing this     register into a map.

    Using __mark_reg_not_init() while NOT allow_ptr_leaks can mitigate this     problem.
