Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm: fix workqueue leak on bind errors Make sure to destroy the workqueue also in case of early errors during bind (e.g. a subcomponent failing to bind). Since commit c3b790ea07a1 ("drm: Manage drm_mode_config_init with drmm_") the mode config will be freed when the drm device is released also when using the legacy interface, but add an explicit cleanup for consistency and to facilitate backporting.

Executive Summary

This vulnerability is a workqueue leak in the Linux kernel's drm/msm component that occurs on bind errors. Specifically, when there are early errors during the binding process of a subcomponent, the workqueue is not properly destroyed, leading to a resource leak. The fix ensures that the workqueue is explicitly destroyed even if binding fails early.

Impact Analysis

The impact of this vulnerability is a resource leak in the Linux kernel, which could lead to increased memory usage or system instability over time if the workqueue is not properly cleaned up during bind errors.

Mitigation Strategies

Apply the patch that fixes the workqueue leak in the drm/msm component of the Linux kernel. This involves updating the kernel to a version that includes the fix for the workqueue leak on bind errors as described in the patchwork link: https://patchwork.freedesktop.org/patch/525093/. Ensuring your system is running an updated kernel version that includes this fix is the immediate mitigation step.
