Worked on the geerlingguy/linux repository to enhance the stability of the Intel iGPU driver by addressing a critical use-after-free vulnerability during device removal. The solution involved replacing the existing cancel_work_sync mechanism with a new disable_work_sync approach and renaming the associated helper function to ivpu_pm_disable_recovery, clarifying its updated role in the power-management workflow. This targeted patch, implemented in C, focused on kernel development and device driver maintenance, reducing the risk of crashes in embedded systems environments. The work was validated to ensure reliability and included clear documentation to support future code audits and ongoing maintainability within the project.
