An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. Due to insufficient input validation, an attacker can tamper with a runtime-accessible EFI variable to cause a dynamic BAR setting to overlap SMRAM. Se descubrió un problema en Insyde InsydeH2O con los kernels 5.0 a 5.5. Debido a una validación de entrada insuficiente, un atacante puede alterar una variable EFI accesible en tiempo de ejecución para provocar que una configuración de BAR dinámica se superponga a SMRAM. • https://www.insyde.com/security-pledge/SA-2023035 • CWE-20: Improper Input Validation •

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI function 0x17 verifies that the output buffer lies within the command buffer but does not verify that output data does not go beyond the end of the command buffer. In particular, the GetFlashTable function is called directly on the Command Buffer before the DataSize is check, leading to possible circumstances where the data immediately following the command buffer could be destroyed before returning a buffer size error. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023027 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
