CVE-2022-49145
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
