- Details

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