CVE-2026-70112
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
Heap-based buffer overflow in Windows Spaceport.sys allows an authorized attacker to execute code locally.
Risk Assessment
An attacker with local access can execute arbitrary code in kernel context, potentially leading to full system takeover.
Recommendation
Immediately apply patches for the Spaceport.sys driver and restrict loading of unsigned drivers.
