CVE-2022-49145 ACPI: CPPC: Avoid out of bounds access when parsing _CPC data

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Avoid out of bounds access when parsing CPC data If the NumEntries field in the CPC return package is less than 2, do not attempt to access the "Revision" element of that package, because it may not be present then...

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...
