Attack-Flow Graph

Executive Summary

This vulnerability is a memory leak in the Linux kernel's drm/amdgpu component related to the hpd_rx_irq_create_workqueue() function. If the creation of the array of work queues to handle hpd_rx_irq offload work fails, the system does not properly clean up by destroying all created workqueues and freeing the allocated memory, leading to a memory leak.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion, which might result in system instability or crashes.
