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 •

An issue was discovered in AhciBusDxe 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 (the CommBuffer+8 location). Se ha detectado un problema en AhciBusDxe en 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 o valida suficientemente el puntero del buffer asignado (la ubicación CommBuffer+8). • 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 •

A vulnerability exists in SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer(QWORD values for CommBuffer). This can be used by an attacker to corrupt data in SMRAM memory and even lead to arbitrary code execution. Existe una vulnerabilidad en la rama SMM (System Management Mode) que registra un manejador SWSMI que no comprueba o valida suficientemente el puntero del buffer asignado (valores QWORD para CommBuffer). Esto puede ser utilizado por un atacante para corromper los datos en la memoria SMRAM e incluso llevar a la ejecución de código arbitrario • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf https://security.netapp.com/advisory/ntap-20220216-0006 https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2021001 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
