03 Feb 2022 — An issue was discovered in SdHostDriver in the kernel 5.0 through 5.5 in Insyde InsydeH2O. There is an SMM callout that allows an attacker to access the System Management Mode and execute arbitrary code. This occurs because of a Numeric Range Comparison Without a Minimum Check. Se ha descubierto un problema en SdHostDriver en el kernel versión 5.0 hasta la versión 5.5 en InsydeH2O. Hay una llamada SMM que permite a un atacante acceder al modo de gestión del sistema y ejecutar código arbitrario. • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
