Known exploited (CISA KEV) first, then by EPSS exploit probability.

• CVE-2017-5753, published 2018-01-04. Medium severity, CVSS 5.6. EPSS: 93.8% chance of exploitation in the next 30 days. Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
• CVE-2024-5660, published 2024-12-10. Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days. Use of Hardware Page Aggregation (HPA) and Stage-1 and/or Stage-2 translation on Cortex-A77, Cortex-A78, Cortex-A78C, Cortex-A78AE, Cortex-A710, Cortex-X1, Cortex-X1C, Cortex-X2, Cortex-X3,…
• CVE-2022-23960, published 2022-03-13. Medium severity, CVSS 5.6. EPSS: 0.5% chance of exploitation in the next 30 days. Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History…
• CVE-2022-25368, published 2022-03-10. Medium severity, CVSS 4.7. EPSS: 0.3% chance of exploitation in the next 30 days. Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history (stored in the CPU BHB) to influence mispredicted branches in the victim's hardware context. Speculation…
