Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Implement bounds
 check for stream encoder creation in DCN401 'stream_enc_regs' 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 'stream_enc_regs' 4 <= 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
