Name of the Vulnerable Software and Affected Versions Insyde InsydeH2O kernel versions 5.0 through 5.6

Description An issue was discovered in PnpSmm, where there is a possible out-of-bounds access in the SMM communication buffer, leading to tampering. The PNP-related SMI sub-functions do not verify data size before getting it from the communication buffer, which could lead to possible circumstances where the data immediately following the command buffer could be destroyed with a fixed value.

Recommendations For kernel 5.0, update to kernel 5.2 v05.28.45 or later. For kernel 5.1, update to kernel 5.2 v05.28.45 or later. For kernel 5.2, update to kernel 5.2 v05.28.45 or later. For kernel 5.3, update to kernel 5.3 v05.37.45 or later. For kernel 5.4, update to kernel 5.4 v05.45.45 or later. For kernel 5.5, update to kernel 5.5 v05.53.45 or later. For kernel 5.6, update to kernel 5.6 v05.60.45 or later.
