CVE-2020-5953
https://notcve.org/view.php?id=CVE-2020-5953
A vulnerability exists in System Management Interrupt (SWSMI) handler of InsydeH2O UEFI Firmware code located in SWSMI handler that dereferences gRT (EFI_RUNTIME_SERVICES) pointer to call a GetVariable service, which is located outside of SMRAM. This can result in code execution in SMM (escalating privilege from ring 0 to ring -2). Se presenta una vulnerabilidad en el manejador de Interrupciones de administración del Sistema (SWSMI) del código del Firmware UEFI de InsydeH2O ubicado en el manejador SWSMI que desreferencia el puntero gRT (EFI_RUNTIME_SERVICES) para llamar a un servicio GetVariable, que es encontrado fuera de la SMRAM. Esto puede resultar en una ejecución de código en SMM (escalando el privilegio del anillo 0 al anillo -2) • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220222-0005 https://www.insyde.com/products https://www.insyde.com/security-pledge •
CVE-2022-24069
https://notcve.org/view.php?id=CVE-2022-24069
An issue was discovered in AhciBusDxe in Insyde InsydeH2O with kernel 5.0 before 05.08.41, 5.1 before 05.16.29, 5.2 before 05.26.29, 5.3 before 05.35.29, 5.4 before 05.43.29, and 5.5 before 05.51.29. An SMM callout vulnerability allows an attacker to hijack the execution flow of code running in System Management Mode. Exploiting this issue could lead to escalating privileges to SMM. Se ha detectado un problema en AhciBusDxe en InsydeH2O con el kernel versión 5.0 anteriores a 05.08.41, versiones 5.1 anteriores a 05.16.29, versiones 5.2 anteriores a 05.26.29, versiones 5.3 anteriores a 05.35.29, versiones 5.4 anteriores a 05.43.29 y versiones 5.5 anteriores a 05.51.29. Una vulnerabilidad en la llamada SMM permite a un atacante secuestrar el flujo de ejecución del código que es ejecutado en el modo de administración del sistema. • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220216-0002 https://www.insyde.com/security-pledge •

An issue was discovered in SdHostDriver in Insyde InsydeH2O with kernel 5.1 before 05.16.25, 5.2 before 05.26.25, 5.3 before 05.35.25, 5.4 before 05.43.25, and 5.5 before 05.51.25. A vulnerability exists in the SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer (CommBufferData). Se ha detectado un problema en SdHostDriver en Insyde InsydeH2O con el kernel 5.1 anteriores a 05.16.25, 5.2 anteriores a 05.26.25, 5.3 anteriores a 05.35.25, 5.4 anteriores a 05.43.25 y 5.5 anteriores a 05.51.25. Se presenta una vulnerabilidad en la rama SMM (System Management Mode) que registra un manejador SWSMI que no comprueba ni valida suficientemente el puntero del búfer asignado (CommBufferData). • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220216-0004 https://www.insyde.com/security-pledge • CWE-787: Out-of-bounds Write •
CVE-2021-41842
https://notcve.org/view.php?id=CVE-2021-41842
An issue was discovered in AtaLegacySmm in the kernel 5.0 before 05.08.46, 5.1 before 05.16.46, 5.2 before 05.26.46, 5.3 before 05.35.46, 5.4 before 05.43.46, and 5.5 before 05.51.45 in Insyde InsydeH2O. Code execution can occur because the SMI handler lacks a CommBuffer check. Se ha detectado un problema en AtaLegacySmm en el kernel 5.0 anteriores a 05.08.46, 5.1 anteriores a 05.16.46, 5.2 anteriores a 05.26.46, 5.3 anteriores a 05.35.46, 5.4 anteriores a 05.43.46 y 5.5 anteriores a 05.51.45 en InsydeH2O. Puede producirse una ejecución de código porque el manejador SMI carece de una comprobación de CommBuffer. • https://security.netapp.com/advisory/ntap-20220223-0002 https://www.insyde.com/security-pledge •
