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 cpcdescptr NULL. CPU0's iteration via foreachpossible_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>] cppcallowfast_switch+0x6a/0xd4 ... Kernel panic - not syncing: Attempted to kill init!
