Summary
In the Linux kernel, the following vulnerability has been resolved: ice: move netif_queue_set_napi to rtnl-protected sections Currently, netif_queue_set_napi() is called from ice_vsi_rebuild() that is not rtnl-locked when called from the reset. This creates the need to take the rtnl_lock just for a single function and complicates the synchronization with .ndo_bpf. At the same time, there no actual need to fill napi-to-queue information at this exact point. Fill napi-to-queue information when opening the VSI and clear it when the VSI is being closed. Those routines are already rtnl-locked. Also, rewrite napi-to-queue assignment in a way that prevents inclusion of XDP queues, as this leads to out-of-bounds writes, such as one below.

This creates the need to take\\nthe rtnl_lock just for a single function and complicates the\\nsynchronization with .ndo_bpf. At the same time, there no actual need to\\nfill napi-to-queue information at this exact point.\\n\\nFill napi-to-queue information when opening the VSI and clear it when the\\nVSI is being closed. Those routines are already rtnl-locked.\\n\\nAlso, rewrite napi-to-queue assignment in a way that prevents inclusion of\\nXDP queues, as this leads to out-of-bounds writes, such as one below.\\n\\n[  +0.000004] BUG: KASAN: slab-out-of-bounds in netif_queue_set_napi+0x1c2/0x1e0\\n[  +0.000012] Write of size 8 at addr ffff889881727c80 by task bash/7047\\n[  +0.000006] CPU: 24 PID: 7047 Comm: bash Not tainted 6.10.0-rc2+ #2\\n[  +0.000004] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0014.082620210524 08/26/2021\\n[  +0.000003] Call Trace:\\n[  +0.000003]  \u003cTASK\u003e\\n[  +0.000002]  dump_stack_lvl+0x60/0x80\\n[  +0.000007]  print_report+0xce/0x630\\n[  +0.000007]  ? __pfx__raw_spin_lock_irqsave+0x10/0x10\\n[  +0.000007]  ? __virt_addr_valid+0x1c9/0x2c0\\n[  +0.000005]  ? netif_queue_set_napi+0x1c2/0x1e0\\n[  +0.000003]  kasan_report+0xe9/0x120\\n[  +0.000004]  ? netif_queue_set_napi+0x1c2/0x1e0\\n[  +0.000004]  netif_queue_set_napi+0x1c2/0x1e0\\n[  +0.000005]  ice_vsi_close+0x161/0x670 [ice]\\n[  +0.000114]  ice_dis_vsi+0x22f/0x270 [ice]\\n[  +0.000095]  ice_pf_dis_all_vsi.constprop.0+0xae/0x1c0 [ice]\\n[  +0.000086]  ice_prepare_for_reset+0x299/0x750 [ice]\\n[  +0.000087]  pci_dev_save_and_disable+0x82/0xd0\\n[  +0.000006]  pci_reset_function+0x12d/0x230\\n[  +0.000004]  reset_store+0xa0/0x100\\n[  +0.000006]  ? __pfx_reset_store+0x10/0x10\\n[  +0.000002]  ? __pfx_mutex_lock+0x10/0x10\\n[  +0.000004]  ? __check_object_size+0x4c1/0x640\\n[  +0.000007]  kernfs_fop_write_iter+0x30b/0x4a0\\n[  +0.000006]  vfs_write+0x5d6/0xdf0\\n[  +0.000005]  ? fd_install+0x180/0x350\\n[  +0.000005]  ? __pfx_vfs_write+0x10/0xA10\\n[  +0.000004]  ? do_fcntl+0x52c/0xcd0\\n[  +0.000004]  ? kasan_save_track+0x13/0x60\\n[  +0.000003]  ? kasan_save_free_info+0x37/0x60\\n[  +0.000006]  ksys_write+0xfa/0x1d0\\n[  +0.000003]  ? __pfx_ksys_write+0x10/0x10\\n[  +0.000002]  ? __x64_sys_fcntl+0x121/0x180\\n[  +0.000004]  ? _raw_spin_lock+0x87/0xe0\\n[  +0.000005]  do_syscall_64+0x80/0x170\\n[  +0.000007]  ? _raw_spin_lock+0x87/0xe0\\n[  +0.000004]  ? __pfx__raw_spin_lock+0x10/0x10\\n[  +0.000003]  ? file_close_fd_locked+0x167/0x230\\n[  +0.000005]  ? syscall_exit_to_user_mode+0x7d/0x220\\n[  +0.000005]  ? do_syscall_64+0x8c/0x170\\n[  +0.000004]  ? do_syscall_64+0x8c/0x170\\n[  +0.000003]  ? do_syscall_64+0x8c/0x170\\n[  +0.000003]  ? fput+0x1a/0x2c0\\n[  +0.000004]  ? filp_close+0x19/0x30\\n[  +0.000004]  ? do_dup2+0x25a/0x4c0\\n[  +0.000004]  ? __x64_sys_dup2+0x6e/0x2e0\\n[  +0.000002]  ? syscall_exit_to_user_mode+0x7d/0x220\\n[  +0.000004]  ? do_syscall_64+0x8c/0x170\\n[  +0.000003]  ? __count_memcg_events+0x113/0x380\\n[  +0.000005]  ? handle_mm_fault+0x136/0x820\\n[  +0.000005]  ? do_user_addr_fault+0x444/0xa80\\n[  +0.000004]  ? clear_bhb_loop+0x25/0x80\\n[  +0.000004]  ? clear_bhb_loop+0x25/0x80\\n[  +0.000002]  entry_SYSCALL_64_after_hwframe+0x76/0x7e\\n[  +0.000005] RIP: 0033:0x7f2033593154\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ice: mover netif_queue_set_napi a secciones protegidas por rtnl Actualmente, netif_queue_set_napi() se llama desde ice_vsi_rebuild() que no est\u00e1 bloqueado por rtnl cuando se llama desde el reinicio.
