CVE-2020-36776 (GCVE-0-2020-36776)

Vulnerability from cvelistv5 – Published: 2024-02-27 18:40 – Updated: 2025-05-04 12:40

Title

thermal/drivers/cpufreq_cooling: Fix slab OOB issue

Summary

In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/cpufreq_cooling: Fix slab OOB issue Slab OOB issue is scanned by KASAN in cpu_power_to_freq(). If power is limited below the power of OPP0 in EM table, it will cause slab out-of-bound issue with negative array index. Return the lowest frequency if limited power cannot found a suitable OPP in EM table to fix this issue.
