CVE-2025-68177
In the Linux kernel, the following vulnerability has been resolved:
cpufreq/longhaul: handle NULL policy in longhaul_exit
longhaul_exit() was calling cpufreq_cpu_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
