Description OSIDB Bzimport 2025-10-07 16:07:45 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix memory leak in hpd_rx_irq_create_workqueue()

If construction of the array of work queues to handle hpd_rx_irq offload
work fails, we need to unwind. Destroy all the created workqueues and
the allocated memory for the hpd_rx_irq_offload_work_queue struct array.
