Chipmaker Intel has confirmed that proprietary source code related to its Alder Lake CPUs has been leaked, following its release by an unknown third-party on 4chan and GitHub last week.

The published content contains Unified Extensible Firmware Interface (UEFI) code for Alder Lake, the company's 12th generation processors that was originally launched in November 2021.

In a statement shared with Tom's Hardware, Intel said the leak doesn't expose "any new security vulnerabilities as we do not rely on obfuscation of information as a security measure."
