Bounds Checking Vulnerability in Linux Kernel Affects Accel/QAIC

CVE-2023-53493

What is CVE-2023-53493?

A vulnerability in the Linux kernel's accel/qaic module arose from inadequate bounds checking during message decoding. When handling messages, the system failed to ensure sufficient space for headers and data, potentially allowing for negative sizing and memory corruption. Fixes implemented focus on validating message lengths and ensuring that header sizes are adequate, incorporating measures to prevent integer overflows. This enhances system stability and security against potential exploits.
