Description
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.
Affected configurations
• insyde insydeh2o (>= 5.0 < 5.2.05.27.27)
• insyde insydeh2o (>= 5.3 < 5.3.05.36.27)
• insyde insydeh2o (>= 5.4 < 5.4.05.44.27)
• insyde insydeh2o (>= 5.5 < 5.5.05.52.27)
