kernel: Linux kernel (net/mlx5): Use-after-free in ECVF vports unload leads to denial of service

A flaw was found in the Linux kernel's net/mlx5 component. A local user could exploit a use-after-free vulnerability during the shutdown process when embedded chip virtual function ECVF vports are unloaded. This occurs because the vport access control list ACL ingress table is not properly...
