  "title": "drm/amd/display: Implement bounds check for stream encoder creation in DCN401",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Implement bounds check for stream encoder creation in DCN401  \u0027stream_enc_regs\u0027 array is an array of dcn10_stream_enc_registers structures. The array is initialized with four elements, corresponding to the four calls to stream_enc_regs() in the array initializer. This means that valid indices for this array are 0, 1, 2, and 3.  The error message \u0027stream_enc_regs\u0027 4 \u003C= 5 below, is indicating that there is an attempt to access this array with an index of 5, which is out of bounds. This could lead to undefined behavior  Here, eng_id is used as an index to access the stream_enc_regs array. If eng_id is 5, this would result in an out-of-bounds access on the stream_enc_regs array.  Thus fixing Buffer overflow error in dcn401_stream_encoder_create  Found by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn401/dcn401_resource.c:1209 dcn401_stream_encoder_create() error: buffer overflow \u0027stream_enc_regs\u0027 4 \u003C= 5",
