Summary
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. UEFI implementations do not correctly protect and validate information contained in the 'MeSetup' UEFI variable. On some systems, this variable can be overwritten using operating system APIs. Exploitation of this vulnerability could potentially lead to denial of service for the platform.
