n the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix array index out of bound error in DCN32 DML [Why&How] LinkCapacitySupport array is indexed with the number of voltage states and not the number of max DPPs. Fix the error by changing the array declaration to use the correct (larger) array size of total number of voltage states.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: se corrige el error de índice de matriz fuera de límite en DCN32 DML [Por qué y cómo] La matriz LinkCapacitySupport está indexada con la cantidad de estados de voltaje y no con la cantidad máxima de DPP. Corrija el error modificando la declaración de la matriz para utilizar el tamaño de matriz correcto (más grande) de la cantidad total de estados de voltaje.
