Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to an unintentional integer overflow in the Linux kernel, specifically in the drm/mediatek component. The problem arises from multiplying two variables of different types, which can lead to an overflow. To fix this, the code has been modified to assign a value to one variable and then multiply the other variable. Additionally, an integer variable has been introduced for multiplier calculations to avoid direct calculations with the dma addr t variable.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
