Memory Mapping Vulnerability in Linux Kernel Affects Device Driver Functionality

CVE-2023-53753

What is CVE-2023-53753?

A vulnerability in the Linux kernel arises from improper memory mapping, specifically resulting in attempts to access non-allocated regions within memory. This problem is particularly significant within the context of device drivers, where it could lead to unstable behavior when allocating GPIO registers from an out-of-bounds array. The issue has been addressed with a patch that corrects the bounds used in the mapping process, ensuring proper memory allocation and enhancing overall system stability.
