Actively Exploited
CISA Known Exploited Vulnerabilities (KEV) Catalog
EPSS (Exploit Prediction Scoring System) estimates a 6.9% chance this CVE is exploited in the wild within the next 30 days — higher than 94% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.
An input validation vulnerability exists in the VBoxDrv.sys driver of Sun xVM VirtualBox which allows attackers to locally execute arbitrary code.
Description
The VBoxDrvNtDeviceControl function in VBoxDrv.sys in Sun xVM VirtualBox before 1.6.4 uses the METHOD_NEITHER communication method for IOCTLs and does not properly validate a buffer associated with the Irp object, which allows local users to gain privileges by opening the \\.\VBoxDrv device and calling DeviceIoControl to send a crafted kernel address.
