Detailed vulnerability description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to a signedness bug in validating the user-supplied number of elements provided by the user in the structure passed to the Kernel driver function. A local attacker can perform a call to an struct method exported from the Kernel driver with the IOService 'com_trusteer_rapportke_v2', trigger stack-based buffer overflow and execute arbitrary code in the context of the service daemon.
Successful exploitation of the vulnerability may result in system compromise.
