58 hardware vulnerabilities: A guide to the threats
Summary
Since January 2018, researchers have discovered over 58 hardware vulnerabilities in processors and memory chips, starting with Meltdown and Spectre, which exploited speculative execution (a CPU performance feature that tries to predict what instructions to run next). These flaws allow attackers to extract sensitive information across security boundaries that normally protect different programs from each other, and fixing them requires a mix of firmware updates (low-level software on hardware chips), BIOS/UEFI updates (firmware that runs when a computer starts), microcode updates (CPU instruction-level fixes), and operating system patches, though some vulnerabilities cannot be completely fixed without replacing the hardware entirely.
Solution / Mitigation
Mitigation strategies mentioned in the source include: (1) operating system updates involving stricter memory isolation (such as Linux's kernel page-table isolation or KPTI); (2) BIOS/UEFI updates to apply CPU microcode fixes; (3) operating system microcode updates applied at every reboot; and (4) firmware updates. The source notes that 'some hardware vulnerabilities are impossible to mitigate completely without releasing a new generation of components,' indicating that complete fixes may require hardware replacement for certain flaws.
