Title
ACPI: CPPC: Fix NULL pointer dereference when nosmp is used
Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: CPPC: Fix NULL pointer dereference when nosmp is used
With nosmp in cmdline, other CPUs are not brought up, leaving
their cpc_desc_ptr NULL. CPU0's iteration via for_each_possible_cpu()
dereferences these NULL pointers, causing panic.
Panic backtrace:
[ 0.401123] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000b8
...
[ 0.403255] [<ffffffff809a5818>] cppc_allow_fast_switch+0x6a/0xd4
...
Kernel panic - not syncing: Attempted to kill init!
