Description
In NrmmDecoder::DecodeSORTransparentContext of cn_NrmmDecoder.cpp, there is a possible out of bounds write due to a heap buffer overflow. This could lead to remote (proximal/adjacent) escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
