CVE-2022-36338
https://notcve.org/view.php?id=CVE-2022-36338
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 •

https://notcve.org/view.php?id=CVE-2022-35894
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 •
CVE-2022-35408
https://notcve.org/view.php?id=CVE-2022-35408
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.) Se ha detectado un problema en InsydeH2O con el kernel versiones 5.0 hasta 5.5. • https://binarly.io/advisories/BRLY-2022-022/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022031 •

https://notcve.org/view.php?id=CVE-2022-35896
An issue SMM memory leak vulnerability in SMM driver (SMRAM was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An attacker can dump SMRAM contents via the software SMI provided by the FvbServicesRuntimeDxe driver to read the contents of SMRAM, leading to information disclosure. Se ha detectado una vulnerabilidad de pérdida de memoria en el controlador SMM (SMRAM) en InsydeH2O con el kernel versiones 5.0 hasta 5.5. Un atacante puede volcar el contenido de la SMRAM por medio del software SMI proporcionado por el controlador FvbServicesRuntimeDxe para leer el contenido de la SMRAM, conllevando a una divulgación de información • https://binarly.io/advisories/BRLY-2022-025/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022034 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2022-35895
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The FwBlockSericceSmm driver does not properly validate input parameters for a software SMI routine, leading to memory corruption of arbitrary addresses including SMRAM, and possible arbitrary code execution. Se ha detectado un problema en InsydeH2O con el kernel versiones 5.0 hasta 5.5. El controlador FwBlockSericceSmm no comprueba correctamente los parámetros de entrada para una rutina SMI de software, conllevando a una corrupción de la memoria de direcciones arbitrarias, incluida la SMRAM, y una posible ejecución de código arbitrario • https://binarly.io/advisories/BRLY-2022-024/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022033 • CWE-787: Out-of-bounds Write •
