Overview

About vulnerability

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:
