Patch availableNumeric truncation error in Windows Resilient File System (ReFS) allows an authorized attacker to execute code locally.
Numeric truncation error in Windows Resilient File System (ReFS) allows an authorized attacker to execute code locally.
Truncation errors occur when a primitive is cast to a primitive of a smaller size and data is lost in the conversion.
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
