Subject: Re: [PATCH] cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate()
Date: Mon, 7 Apr 2025 11:06:08 +0200 [thread overview]
Message-ID: <e8e785a8-5f8f-4ea2-a150-2837f47b4472@web.de> (raw)
In-Reply-To: <20250405092314.76297-1-bsdhenrymartin@gmail.com>
> cpufreq_cpu_get_raw() can return NULL when the target CPU is not present
> in the policy->cpus mask. scpi_cpufreq_get_rate() does not check for
> this case, which results in a NULL pointer dereference.
