CVE-2021-42113

An issue was discovered in StorageSecurityCommandDxe in Insyde InsydeH2O with Kernel 5.1 before 05.14.28, Kernel 5.2 before 05.24.28, and Kernel 5.3 before 05.32.25. An 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.
