Name of the Vulnerable Software and Affected Versions Intel(R) 6th Generation Core Processors and greater, supporting SGX

Description The issue is related to insufficient memory protection in Intel processors, specifically those supporting Software Guard eXtensions (SGX) technology. This could allow a privileged user to potentially enable escalation of privilege via local access. The vulnerability involves a buffer overflow in memory, which may permit an attacker to elevate their privileges.

Recommendations For Intel(R) 6th Generation Core Processors and greater, supporting SGX, consider restricting local access to minimize the risk of exploitation until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
