CVE-2024-38573

HighCVSS 7.5/10Last modified Jun 17, 2026

Description

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

cppc_cpufreq: Fix possible null pointer dereference

cppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from different places with various parameters. So cpufreq_cpu_get() can return null as 'policy' in some circumstances. Fix this bug by adding null return check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
