Use-After-Free Vulnerability in Linux Kernel's MPC52xx SPI Module

CVE-2024-50051

What is CVE-2024-50051?

A use-after-free vulnerability exists in the Linux kernel's MPC52xx SPI module. When the module is removed, it can release resources inappropriately while a related work item is still active. Specifically, if the removal sequence occurs without canceling the active work, it can lead to a scenario where the freed resources are accessed, resulting in instability or potential security risks. The vulnerability has been addressed by ensuring that the work is properly canceled before the cleanup processes are executed in the module's removal function.
