CVE-2019-1325

Status: ModifiedMedium (5.5)—

An elevation of privilege vulnerability exists in the Windows redirected drive buffering system (rdbss.sys) when the operating system improperly handles specific local calls within Windows 7 for 32-bit systems, aka 'Windows Redirected Drive Buffering System Elevation of Privilege Vulnerability'.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
