net/mlx5: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()

State: Published
Severity: Not scored

Description

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.
