Description
In the Linux kernel, the following vulnerability has been resolved:
octeon_ep: Fix memory leak in octep_device_setup()
In octep_device_setup(), if octep_ctrl_net_init() fails, the function
returns directly without unmapping the mapped resources and freeing the
allocated configuration memory.
Fix this by jumping to the unsupported_dev label, which performs the
necessary cleanup. This aligns with the error handling logic of other
paths in this function.
Compile tested only. Issue found using a prototype static analysis tool
and code review.
