kernel: drm/nouveau/kms/nv50-: init hpd_irq_lock for PIOR DP
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/kms/nv50-: init hpd_irq_lock for PIOR DP
Fixes OOPS on boards with ANX9805 DP encoders.
A flaw was found in the Linux kernel's nouveau graphics driver for NVIDIA GPUs. The hpd_irq_lock spinlock is not initialized for PIOR (Parallel Interface Output Resource) DisplayPort connectors. This missing initialization causes a kernel oops on systems with ANX9805 DP encoders when hotplug detection operations access the uninitialized lock.
Statement: This issue affects a narrow subset of systems: those with NVIDIA graphics cards using the nouveau driver combined with ANX9805 DisplayPort encoder hardware. Most users will not encounter this bug as it requires s
