Computer Associates Host Intrusion Prevention System (HIPS) drivers (1) Core kmxstart.sys 6.5.4.31 and (2) Firewall kmxfw.sys 6.5.4.10 allow local users to gain privileges by using certain privileged IOCTLs to modify callback function pointers.

Unspecified vulnerability in the kmxfw.sys driver in CA Host-Based Intrusion Prevention System (HIPS) r8, as used in CA Internet Security Suite and Personal Firewall, allows remote attackers to cause a denial of service via unknown vectors, related to "insufficient validation."

The kmxfw.sys driver in CA Host-Based Intrusion Prevention System (HIPS) r8, as used in CA Internet Security Suite and Personal Firewall, does not properly verify IOCTL requests, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted request.
