Background for this topic.
Intel Corporation is a semiconductor designer whose processors, chipsets, firmware, and platform components underpin many servers, PCs, and embedded systems. In security news, the tag usually concerns vulnerabilities or mitigations affecting this hardware and its supporting software, rather than “intel” meaning threat intelligence.
Security impact can arise below the operating-system boundary: speculative-execution flaws may expose data through side channels, while firmware or platform-management weaknesses can enable privilege escalation or persistence in some configurations. Intel security advisories, operating-system updates, BIOS or UEFI releases, and microcode updates (small processor-control patches) therefore form a coordinated remediation chain. Administrators should inventory affected processor generations and firmware versions, apply trusted updates where applicable, and assess performance or compatibility trade-offs. Researchers and defenders may also need to distinguish hardware limitations from software bugs when investigating suspected exploitation.
Exposed code included private key for Intel Boot Guard, meaning it can no longer be trusted, according to a researcher.
Gurus say source includes secret hardware info, private signing key for Boot Guard protection Source code for the BIOS used with Intel's 12th-gen Core processors has been leaked online, possibly including details of undocumented model-specific registers (MSRs) and even the private signing key for Intel's Boot Guard security technology.…
Cyber-criminals could use the leaked source code to help launch attacks
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
