An issue was discovered in Insyde InsydeH2O Kernel 5.0 through 05.08.41, Kernel 5.1 through 05.16.41, Kernel 5.2 before 05.23.22, and Kernel 5.3 before 05.32.22. An Int15ServiceSmm SMM callout vulnerability allows an attacker to hijack execution flow of code running in System Management Mode. Exploiting this issue could lead to escalating privileges to SMM.
