Description
A flaw was found in the Linux kernel's hns3 network driver. This vulnerability allows a local attacker to cause a kernel crash, leading to a Denial of Service (DoS), when a devlink reload operation is performed during the physical function (PF) initialization process. This occurs because the reload process attempts to access hardware resources before they are fully initialized, disrupting system availability.
