Description
A vulnerability in the Linux kernel's cpufreq driver for brcmstb-avs-cpufreq was fixed by adding a check for the return value of cpufreq_cpu_get, which may return NULL. Without this check, a NULL pointer dereference could occur, leading to a denial of service. The issue affects certain versions of the linux-azure kernel and has been addressed in specific fixed releases.
