In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: Fix a potential leak in nfp_tunnel_add_shared_mac()
ida_simple_get() returns an id between min (0) and max (NFP_MAX_MAC_INDEX)
inclusive.
So NFP_MAX_MAC_INDEX (0xff) is a valid id.
In order for the error handling path to work correctly, the ‘invalid’
value for ‘ida_idx’ should not be in the 0…NFP_MAX_MAC_INDEX range,
inclusive.
So set it to -1.
