Executive Summary

This vulnerability is an integer overflow in the Linux kernel's fpga subsystem, specifically in the dfl_feature_ioctl_set_irq() function. On 32-bit systems, the multiplication of hdr.count by sizeof(s32) can overflow, which may lead to memory corruption. The issue was fixed by using a safer method (array_size()) to prevent the overflow.

Impact Analysis

The integer overflow can cause memory corruption, which may lead to system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges on affected 32-bit Linux systems.
