CVE-2022-32475

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the VariableRuntimeDxe 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 issue was fixed in the kernel, which also protected chipset and OEM chipset code.

Summary		(es) Se descubrió un problema en Insyde InsydeH2O con los kernels 5.0 a 5.5. Los ataques DMA al búfer compartido VariableRuntimeDxe utilizado por el código SMM y no SMM podrían causar problemas de condiciones de ejecución de TOCTOU que podrían conducir a la corrupción de SMRAM y a la escalada de privilegios. Este problema se solucionó en el kernel, que también protegía el chipset y el código del chipset OEM.
