Fedora 42 Looking To Package Intel SGX Software Stack
Fedora stakeholders are evaluating supporting an Intel Software Guard Extensions (SGX) software stack with next year's Fedora 42 release.
But it's been controversial due to a number of published security vulnerabilities around it over the years and the idea of "trusted" execution in the open-source world rubbing some users the wrong way, especially if SGX is used for purposes of Digital Rights Management. "The Intel SGX technology enables creation of execution enclaves, whose memory is encrypted and thus protected from all other code running on the CPU, including SMM, firmware, kernel and userspace. The primary feature that will leverage SGX in a subsequent Fedora release is expected to be Intel TDX, which provides confidential virtual machines, and is in the process of being integrated with QEMU and Linux/KVM."
