Description
In the Linux kernel, the following vulnerability has been resolved: drm/tegra: Add call to put_pid() Add a call to put_pid() corresponding to get_task_pid(). host1x_memory_context_alloc() does not take ownership of the PID so we need to free it here to avoid leaking.

Executive Summary

This vulnerability is related to the Linux kernel's drm/tegra component where a call to put_pid() was missing after get_task_pid(). The function host1x_memory_context_alloc() does not take ownership of the PID, so without the put_pid() call, the PID was not freed properly, leading to a resource leak.

Impact Analysis

The impact of this vulnerability is a potential resource leak in the Linux kernel due to not freeing a PID properly. This could lead to increased memory usage or resource exhaustion over time, potentially affecting system stability or performance.
