      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5e: Fix cleanup null-ptr deref on encap lock\n\nDuring module is unloaded while a peer tc flow is still offloaded,\nfirst the peer uplink rep profile is changed to a nic profile, and so\nneigh encap lock is destroyed. Next during unload, the VF reps netdevs\nare unregistered which causes the original non-peer tc flow to be deleted,\nwhich deletes the peer flow. The peer flow deletion detaches the encap\nentry and try to take the already destroyed encap lock, causing the\nbelow trace.\n\nFix this by clearing peer flows during tc eswitch cleanup\n(mlx5e_tc_esw_cleanup()).\n\nRelevant trace:\n[ 4316.837128] BUG: kernel NULL pointer dereference, address: 00000000000001d8\n[ 4316.842239] RIP: 0010:__mutex_lock+0xb5/0xc40\n[ 4316.851897] Call Trace:\n[ 4316.852481]  <TASK>\n[ 4316.857214]  mlx5e_rep_neigh_entry_release+0x93/0x790 [mlx5_core]\n[ 4316.858258]  mlx5e_rep_encap_entry_detach+0xa7/0xf0 [mlx5_core]\n[ 4316.859134]  mlx5e_encap_dealloc+0xa3/0xf0 [mlx5_core]\n[ 4316.859867]  clean_encap_dests.part.0+0x5c/0xe0 [mlx5_core]\n[ 4316.860605]  mlx5e_tc_del_fdb_flow+0x32a/0x810 [mlx5_core]\n[ 4316.862609]  __mlx5e_tc_del_fdb_peer_flow+0x1a2/0x250 [mlx5_core]\n[ 4316.863394]  mlx5e_tc_del_flow+0x(/0x630 [mlx5_core]\n[ 4316.864090]  mlx5e_flow_put+0x5f/0x100 [mlx5_core]\n[ 4316.864771]  mlx5e_delete_flower+0x4de/0xa40 [mlx5_core]\n[ 4316.865486]  tc_setup_cb_reoffload+0x20/0x80\n[ 4316.865905]  fl_reoffload+0x47c/0x510 [cls_flower]\n[ 4316.869181]  tcf_block_playback_offloads+0x91/0x1d0\n[ 4316.869649]  tcf_block_unbind+0xe7/0x1b0\n[ 4316.870049]  tcf_block_offload_cmd.isra.0+0x1ee/0x270\n[ 4316.879266]  tcf_block_offload_unbind+0x61/0xa0\n[ 4316.879711]  __tcf_block_put+0xa4/0x310",
