In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: fix a potential double-free in fsanycreate_groups
When kcalloc() for ft->g succeeds but kvzalloc() for in fails, fsanycreategroups() will free ft->g. However, its caller fsanycreatetable() will free ft->g again through calling mlx5edestroyflowtable(), which will lead to a double-free. Fix this by setting ft->g to NULL in fsanycreategroups().
