In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix deadlock during netdev reset with active connections
Resolve deadlock that occurs when user executes netdev reset while RDMA
applications (e.g., rping) are active. The netdev reset causes ice
driver to remove irdma auxiliary driver, triggering device_delete and
subsequent client removal. During client removal, uverbs_client waits
for QP reference count to reach zero while cma_client holds the final
reference, creating circular dependency and indefinite wait in iWARP
mode. Skip QP reference count wait during device reset to prevent
deadlock.
