Out-of-bounds Read in Intel(r) Converged Security And Management Engine (Csme) Firmware (Fw)

CVE-2025-27708

Out-of-bounds read in the firmware for some Intel(R) Converged Security and Management Engine (CSME) Firmware (FW) within Ring 0: Kernel may allow an information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
