Details

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).
