"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Implement bounds check for stream encoder creation in DCN301\n\n'stream_enc_regs' array is an array of dcn10_stream_enc_registers\nstructures. The array is initialized with four elements, corresponding\nto the four calls to stream_enc_regs() in the array initializer. This\nmeans that valid indices for this array are 0, 1, 2, and 3.\n\nThe error message 'stream_enc_regs' 4 <= 5 below, is indicating that\nthere is an attempt to access this array with an index of 5, which is\nout of bounds. This could lead to undefined behavior\n\nHere, eng_id is used as an index to access the stream_enc_regs array. If\neng_id is 5, this would result in an out-of-bounds access on the\nstream_enc_regs array.\n\nThus fixing Buffer overflow error in dcn301_stream_encoder_create\nreported by Smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn301/dcn301_resource.c:1011 dcn301_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5"

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: drm/amd/display: implementar la verificaci\u00f3n de los l\u00edmites para la creaci\u00f3n del codificador de flujo en la matriz DCN301 'stream_enc_regs' es una matriz de estructuras dcn10_stream_enc_registers. La matriz se inicializa con cuatro elementos, correspondientes a las cuatro llamadas a stream_enc_regs() en el inicializador de la matriz. Esto significa que los \u00edndices v\u00e1lidos para esta matriz son 0, 1, 2 y 3. El mensaje de error 'stream_enc_regs' 4 <= 5 a continuaci\u00f3n indica que hay un intento de acceder a esta matriz con un \u00edndice de 5, que no est\u00e1 disponible. de los l\u00edmites. Esto podr\u00eda provocar un comportamiento indefinido. Aqu\u00ed, eng_id se utiliza como \u00edndice para acceder a la matriz stream_enc_regs. Si eng_id es 5, esto dar\u00eda como resultado un acceso fuera de los l\u00edmites en la matriz stream_enc_regs.
