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).
