CVE-2021-47313

The Linux kernel contains a memory leak vulnerability in the cpufreq: CPPC component, specifically within the cppc_cpufreq_cpu_init function. The issue occurs because the system allocates resources but fails to free them during policy ->init() failures. This results in uncontrolled resource co...

CVE-2024-35995

A vulnerability was found in the ACPI subsystem's CPPC driver in the Linux kernel. This issue occurs due to the mishandling of memory access bit width during performance capability calculations, which can lead to misaligned memory accesses and cause kernel panics on affected platforms...

CVE-2024-35995

CVE-2024-35995 describes a Linux kernel issue where the ACPI CPPC code misread system memory by relying on bit_width, risking incorrect memory access. The fix switches to using access_width for size calculation and reads/writes using an offset and width, with a fallback to bit_width if access_wid...
