Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix coverity issue with unintentional integer overflow 1. Instead of multiplying 2 variable of different types. Change to
assign a value of one variable and then multiply the other variable. 2. Add a int variable for multiplier calculation instead of calculating
different types multiplier with dma_addr_t variable directly.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/mediatek: soluciona el problema de cobertura con desbordamiento de enteros involuntario 1. En lugar de multiplicar 2 variables de diferentes tipos. Cambie para asignar un valor a una variable y luego multiplique la otra variable. 2. Agregue una variable int para el cálculo del multiplicador en lugar de calcular diferentes tipos de multiplicadores con la variable dma_addr_t directamente.
