Out-of-bounds Shift Vulnerability in Linux Kernel Affecting Comedi Driver

CVE-2025-38483

What is CVE-2025-38483?

A vulnerability exists in the Linux kernel's Comedi driver that can allow an attacker to trigger a bit shift operation using unchecked user-supplied input. Specifically, the potential for an out-of-bounds shift arises from validation issues around the IRQ number, which could lead to unexpected behavior or exploitation. Developers are urged to implement strict input validation to ensure that the shift amount is within the valid range before performing any operations.
