CVSS v3.1
Official Description
srvloc.sys in Novell Client for Windows before 4.91 SP3 allows remote attackers to cause an unspecified denial of service via a crafted packet to port 427 that triggers an access of pageable or invalid addresses using a higher interrupt request level (IRQL) than necessary.
Technical Analysis
CVE-2006-6307 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
