Linux Kernel Vulnerability in cdns3 USB Controller by Freescale

CVE-2023-53287

What is CVE-2023-53287?

A flaw has been identified in the Linux kernel related to the cdns3 USB controller, where the active state of the device is incorrectly managed during the resume process. This oversight allows device scheduling during atomic operations, leading to potential kernel warnings and unstable behavior. Specifically, calls to pm_runtime_set_active must be handled outside of the spin lock to prevent disruptions to the struct cdns data structure, thus ensuring smoother operation and reliability in the kernel.
