Detailsinfo

A vulnerability, which was classified as problematic, was found in Intel CSME, TXE and Server Platform Services (the affected version is unknown). Affected is an unknown code of the component Subsystem. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Integer overflow in subsystem for Intel(R) CSME versions before 11.8.77, 11.12.77, 11.22.77 and Intel(R) TXE versions before 3.1.75, 4.0.25 and Intel(R) Server Platform Services (SPS) versions before SPS_E5_04.01.04.380.0, SPS_SoC-X_04.00.04.128.0, SPS_SoC-A_04.00.04.211.0, SPS_E3_04.01.04.109.0, SPS_E3_04.08.04.070.0 may allow a privileged user to potentially enable denial of service via local access.
