MediumCVSS 6.8Exploitation Probability (EPSS)
Low risk33th percentile - higher than 33% of all known CVEs
Summary
A heap-based buffer overflow in Windows Resilient File System (ReFS) allows an unauthorized attacker to execute code via a physical attack.
Risk Assessment
A physical attack could lead to full system compromise, posing a serious threat to data integrity and availability.
Recommendation
Restrict physical access to systems using ReFS and apply the principle of least privilege.
