Description

Trusty TLK contains a vulnerability in the NVIDIA TLK kernel’s tz_map_shared_mem function where an integer overflow on the size parameter causes the request buffer and the logging buffer to overflow, allowing writes to arbitrary addresses within the kernel.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
