CVE-2022-49145

CVE-2022-49145 affects the Linux kernel's ACPI CPPC parsing of _CPC data. The root cause is an out-of-bounds access when the NumEntries field is less than 2, which could lead to improper access of the Revision element. A fix has been implemented in the kernel to avoid this access. The vulnerabili...
