What is CVE-2022-24350?

CVE-2022-24350 is a medium-severity memory corruption vulnerability in Insyde Insydeh2o, published on 12 Apr 2023. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI function 0x17 verifies that the output buffer lies within the command buffer but does not verify that output data does not go beyond the end of the command buffer. In particular, the GetFlashTable function is called directly on the Command Buffer before the DataSize is check, leading to possible circumstances where the data immediately following the command buffer could be destroyed before returning a buffer size error.
