CVE-2022-48657

HIGH

Linux Kernel 5.7-5.10.150 5.11.0-5.15.71 5.16.0-5.19.12 - Integer Overflow in AMU Frequency Invariance Setup

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: arm64: topology: fix possible overflow in amu_fie_setup() cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*, while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'. Multiplying max frequency by 1000 can potentially result in overflow -- multiplying by 1000ULL instead should avoid that... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
