Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cppccpufreq: Fixed a possible null pointer dereferencing issue. The functions cppccpufreqgetrate and hiicppccpufreqgetrate can be called from different locations with various parameters. Therefore, cpufreqcpuget may return null a...

The vulnerability of the functions get_perf_level_count() and cppc_get_cpu_power() in the driver/cpufreq/cppc_cpufreq.c module, a frequency scaling driver for Linux processors, allows a hacker to trigger a service failure.

The vulnerability of the getperflevelcount and cppcgetcpupower functions in the drivers/cpufreq/cppccpufreq.c driver for scaling kernel frequency in Linux operating systems is related to copying buffers without checking their size a classic buffer overflow attack. Exploiting this vulnerability...
