Linux Kernel Denial of Service Vulnerability in Input Drivers

CVE-2022-48619

Summary

A vulnerability affecting the Linux kernel prior to version 5.17.10 arises from an issue in the input drivers, specifically in the input.c file. The vulnerability occurs when the input_set_capability function fails to appropriately manage scenarios where an event code exists outside of an expected bitmap range. This mishandling can lead to a denial of service condition, resulting in a system panic that disrupts normal operations. Affected systems are at risk if they utilize vulnerable kernel versions, making timely updates and patches essential for maintaining security integrity.
