In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix ECVF vports unload on shutdown flow Fix shutdown flow UAF when a virtual function is created on the embedded chip (ECVF) of a BlueField device. In such case the vport acl ingress table is not properly destroyed. ECVF functionality is independent of ecpf_vport_exists capability and thus functions mlx5_eswitch_(enable|disable)_pf_vf_vports() should not test it when enabling/disabling ECVF vports. kernel log: [] refcount_t: underflow; use-after-free.
