kernel: Linux kernel: Denial of Service and information disclosure via undefined bit shift in drm/ttm

A flaw was found in the Linux kernel's drm/ttm component. A local user could exploit an undefined behavior in bit shifting, specifically when a signed 32-bit value is shifted by 31 bits, which cannot be represented in an 'int' type. This vulnerability could lead to local information disclosure,...
