The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005028 advisory.

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

    powerpc/mm: Fix lockup on kernel exec fault

    The powerpc kernel is not prepared to handle exec faults from kernel.
    Especially, the function is_exec_fault() will return 'false' when an     exec fault is taken by kernel, because the check is based on reading     current->thread.regs->trap which contains the trap from user.

    For instance, when provoking a LKDTM EXEC_USERSPACE test,     current->thread.regs->trap is set to SYSCALL trap (0xc00), and     the fault taken by the kernel is not seen as an exec fault by     set_access_flags_filter().

    Commit d7df2443cd5f (powerpc/mm: Fix spurious segfaults on radix     with autonuma) made it clear and handled it properly. But later on     commit d3ca587404b3 (powerpc/mm: Fix reporting of kernel execute     faults) removed that handling, introducing test based on error_code.
    And here is the problem, because on the 603 all upper bits of SRR1     get cleared when the TLB instruction miss handler bails out to ISI.

    Until commit cbd7e6ca0210 (powerpc/fault: Avoid heavy     search_exception_tables() verification), an exec fault from kernel     at a userspace address was indirectly caught by the lack of entry for     that address in the exception tables. But after that commit the     kernel mainly relies on KUAP or on core mm handling to catch wrong     user accesses. Here the access is not wrong, so mm handles it.
    It is a minor fault because PAGE_EXEC is not set,     set_access_flags_filter() should set PAGE_EXEC and voila.
    But as is_exec_fault() returns false as explained in the beginning,     set_access_flags_filter() bails out without setting PAGE_EXEC flag,     which leads to a forever minor exec fault.

    As the kernel is not prepared to handle such exec faults, the thing to     do is to fire in bad_kernel_fault() for any exec fault taken by the     kernel, as it was prior to commit d3ca587404b3.

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.
