Descriptions
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix incorrect mpc_combine array size [why]
MAX_SURFACES is per stream, while MAX_PLANES is per asic. The
mpc_combine is an array that records all the planes per asic. Therefore
MAX_PLANES should be used as the array size. Using MAX_SURFACES causes
array overflow when there are more than 3 planes. [how]
Use the MAX_PLANES for the mpc_combine array size.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: corrige el tamaño incorrecto de la matriz mpc_combine [por qué] MAX_SURFACES es por flujo, mientras que MAX_PLANES es por asic. mpc_combine es una matriz que registra todos los planos por asic. Por lo tanto, se debe utilizar MAX_PLANES como tamaño de matriz. El uso de MAX_SURFACES provoca el desbordamiento de la matriz cuando hay más de 3 planos. [cómo] Utilice MAX_PLANES para el tamaño de matriz mpc_combine.
