The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990809 advisory.

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

    riscv: Use READ_ONCE_NOCHECK in imprecise unwinding stack mode

    When CONFIG_FRAME_POINTER is unset, the stack unwinding function     walk_stackframe randomly reads the stack and then, when KASAN is enabled,     it can lead to the following backtrace:

Note that Nessus has not tested for this issue 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-2025-992949 advisory.

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

    riscv: Use READ_ONCE_NOCHECK in imprecise unwinding stack mode

    When CONFIG_FRAME_POINTER is unset, the stack unwinding function     walk_stackframe randomly reads the stack and then, when KASAN is enabled,     it can lead to the following backtrace:
