Summary
cpufreq/longhaul: handle NULL policy in longhaul_exit
Details

In the Linux kernel, the following vulnerability has been resolved:

cpufreq/longhaul: handle NULL policy in longhaul_exit

longhaulexit() was calling cpufreqcpu_get(0) without checking for a NULL policy pointer. On some systems, this could lead to a NULL dereference and a kernel warning or panic.

This patch adds a check using unlikely() and returns early if the policy is NULL.

Bugzilla: #219962
