"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-407380 advisory.

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

    firmware: arm_scpi: Check the DVFS OPP count returned by the firmware

    Fix a kernel crash with the below call trace when the SCPI firmware
    returns OPP count of zero.

    dvfs_info.opp_count may be zero on some platforms during the reboot
    test, and the kernel will crash after dereferencing the pointer to
    kcalloc(info->count, sizeof(*opp), GFP_KERNEL).
