CVE-2022-0005: 
Linux Fedora vulnerability analysis and mitigation

Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with SGX was identified as CVE-2022-0005. This vulnerability allows an unprivileged user to potentially enable information disclosure through physical access. The vulnerability was discovered and assigned on October 15, 2021, affecting specific Intel processors equipped with SGX technology (Intel Advisory, NVD).

The vulnerability involves the JTAG (Joint Test Action Group) interface, which is a hardware testing and debugging interface present in Intel processors. When exploited, it allows unauthorized access to sensitive information through physical probing of the JTAG interface on processors equipped with Intel SGX (Software Guard Extensions) technology (Intel Advisory).

The vulnerability could lead to information disclosure if successfully exploited. Given that it requires physical access to the JTAG interface, the impact is limited to scenarios where an attacker has direct physical access to the hardware (NVD).

Intel has acknowledged this vulnerability and provided information through their security advisory INTEL-SA-00614. Given the nature of the vulnerability requiring physical access, implementing proper physical security measures and restricting access to hardware components is crucial (Intel Advisory).
