An issue was discovered in Kernel 5.x in Insyde InsydeH2O, affecting HddPassword. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses. Se ha descubierto un problema en el Kernel versión 5.x de InsydeH2O, que afecta a HddPassword. Los servicios SMI de software que utilizan la función Communicate() del EFI_SMM_COMMUNICATION_PROTOCOL no comprueban si la dirección del búfer es válida, lo que permite el uso de direcciones de SMRAM, MMIO o del núcleo del SO • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220222-0004 https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022014 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 https://security.netapp.com/advisory/ntap-20220222-0001 https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022023 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

An issue was discovered in Insyde InsydeH2O with Kernel 5.0 before 05.08.42, Kernel 5.1 before 05.16.42, Kernel 5.2 before 05.26.42, Kernel 5.3 before 05.35.42, Kernel 5.4 before 05.42.51, and Kernel 5.5 before 05.50.51. An SMM memory corruption vulnerability in FvbServicesRuntimeDxe allows a possible attacker to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM. Se ha descubierto un problema en InsydeH2O con el Kernel versión 5.0 antes de 05.08.42, el Kernel 5.1 antes de 05.16.42, el Kernel versión 5.2 antes de 05.26.42, el Kernel versión 5.3 antes de 05.35.42, el Kernel versión 5.4 antes de 05.42.51 y el Kernel versión 5.5 antes de 05.50.51. Una vulnerabilidad de corrupción de memoria SMM en FvbServicesRuntimeDxe permite a un posible atacante escribir datos fijos o predecibles en la SMRAM. • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220216-0007 https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022012 • CWE-787: Out-of-bounds Write •

An issue was discovered in AhciBusDxe in the kernel 5.0 through 5.5 in Insyde InsydeH2O. Because of an Untrusted Pointer Dereference that causes SMM memory corruption, an attacker may be able to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM. Se descubrió un problema en AhciBusDxe en el kernel versión 5.0 hasta la versión 5.5 en InsydeH2O. Debido a una desviación de puntero no fiable que provoca la corrupción de la memoria de SMM, un atacante puede ser capaz de escribir datos fijos o predecibles en SMRAM. • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220222-0003 https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022024 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
