In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()
When the reverse entry is found but its counter is already being
released, refcount_inc_not_zero() fails and the reference taken by
mlx5_tc_ct_entry_get() is never dropped before falling through to
create_counter. Drop it so the reverse entry is not kept alive forever
by a shared counter lookup that did not use it.
