Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/sysfb: Avoid possible truncation with calculating visible size
Calculating the visible size of the system framebuffer can result in truncation of the result. The calculation uses 32-bit arithmetics, which can overflow if the values for height and stride are large. Fix the issue by multiplying with mul_u32_u32().
