Linux Kernel Zynqmp DisplayPort Integer Overflow Vulnerability

A potential integer overflow vulnerability has been identified in the Linux kernel's Zynqmp DisplayPort implementation, specifically within the 'zynqmp_dp_rate_get()' function. The issue arises when a 32-bit expression, 'drm_dp_bw_code_to_link_rate(dp->test.bw_code) * 10000', is evaluated, leading to the possibility of an overflow. This vulnerability has been addressed by changing the constant to a compatible 64-bit type.

Impact

Exploitation of this vulnerability could lead to an integer overflow, potentially allowing for unexpected behavior or manipulation of data within the affected application.
