The vulnerability is caused due to an error in the "KmxSbx.sys" kernel driver when processing IOCTLs and can be exploited to cause a buffer overflow via e.g. overly large data buffer (greater than 65535 bytes) sent to the 0x88000080 IOCTL. Successful exploitation allows execution of arbitrary code in the kernel. The vulnerability is confirmed in CA Internet Security Suite Plus 2010 (KmxSbx.sys 6.2.0.23). Other versions may also be affected. SOLUTION: Grant access to trusted users only.
