https://notcve.org/view.php?id=CVE-2022-32470
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the FwBlockServiceSmm shared buffer used by SMM and non-SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the firmware block services data to SMRAM before checking it. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023002 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An SMM memory corruption vulnerability in the FvbServicesRuntimeDxe driver allows an attacker to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM. Se ha detectado un problema en Insyde InsydeH2O con el kernel versiones 5.0 hasta 5.5. Una vulnerabilidad de corrupción de memoria SMM en el controlador FvbServicesRuntimeDxe permite a un atacante escribir datos fijos o predecibles en la SMRAM. • https://binarly.io/advisories/BRLY-2022-026/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022035 • CWE-20: Improper Input Validation •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An SMM callout vulnerability in the SMM driver FwBlockServiceSmm, creating SMM, leads to arbitrary code execution. An attacker can replace the pointer to the UEFI boot service GetVariable with a pointer to malware, and then generate a software SMI. Se ha detectado un problema en InsydeH2O con el kernel 5.0 hasta 5.5. Una vulnerabilidad de llamada SMM en el controlador SMM FwBlockServiceSmm, que crea SMM, conlleva a una ejecución de código arbitrario. • https://binarly.io/advisories/BRLY-2022-017/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022029 •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The SMI handler for the FwBlockServiceSmm driver uses an untrusted pointer as the location to copy data to an attacker-specified buffer, leading to information disclosure. Se ha detectado un problema en InsydeH2O con el kernel versiones 5.0 hasta 5.5. El controlador SMI para el controlador FwBlockServiceSmm usa un puntero que no es confiable como ubicación para copiar datos en un búfer especificado por el atacante, conllevando a una divulgación de información • https://binarly.io/advisories/BRLY-2022-018/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022030 • CWE-401: Missing Release of Memory after Effective Lifetime •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An SMM callout vulnerability in the SMM driver in UsbLegacyControlSmm leads to possible arbitrary code execution in SMM and escalation of privileges. An attacker could overwrite the function pointers in the EFI_BOOT_SERVICES table before the USB SMI handler triggers. (This is not exploitable from code running in the operating system.)
