CVE-2018-6963

Status: ModifiedMedium (5.5)—

VMware Workstation (14.x before 14.1.2) and Fusion (10.x before 10.1.2) contain multiple denial-of-service vulnerabilities that occur due to NULL pointer dereference issues in the RPC handler. Successful exploitation of these issues may allow an attacker with limited privileges on the guest machine trigger a denial-of-Service of their guest machine.

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).
