CVE-2023-53064: iavf: fix hang on reboot with ice

In the Linux kernel, the following vulnerability has been resolved: iavf: fix hang on reboot with ice When a system with E810 with existing VFs gets rebooted the following hang may be observed. Pid 1 is hung in iavf_remove(), part of a network driver: PID: 1 TASK: ffff965400e5a340 CPU: 24 COMMAND: "systemd-shutdow" #0 [ffffaad04005fa50] __schedule at ffffffff8b3239cb #1 [ffffaad04005fae8] schedule at ffffffff8b323e2d #2 [ffffaad04005fb00] schedule_hrtimeout_range_clock at ffffffff8b32cebc #3 [ffffaad04005fb80] usleep_range_state at ffffffff8b32c930 #4 [ffffaad04005fbb0] iavf_remove at ffffffffc12b9b4c [iavf] #5 [ffffaad04005fbf0] pci_device_remove at ffffffff8add7513 #6 [ffffaad04005fc10] device_release_driver_internal at ffffffff8af08baa #7 [ffffaad04005fc40] pci_stop_bus_device at ffffffff8adcc5fc #8 [ffffaad04005fc60] pci_stop_and_remove_bus_device at ffffffff8adcc81e #9 [ffffaad04005fc70] pci_iov_remove_virtfn at ffffffff8adf9429 #10 [ffffaad04005fca8] sriov_disable at ffffffff8adf98e4 #11 [ffffaad04005fcc8] ice_free_vfs at ffffffffc04bb2c8 [ice] #12 [ffffaad04005fd10] ice_remove at ffffffffc04778fe [ice] #13 [ffffaad04005fd38] ice_shutdown at ffffffffc0477946 [ice] #14 [ffffaad04005fd50] pci_device_shutdown at ffffffff8add58f1 #15 [ffffaad04005fd70] device_shutdown at ffffffff8af05386 #16 [ffffaad04005fd98] kernel_restart at ffffffff8a92a870 #17 [ffffaad04005fda8] __do_sys_reboot at ffffffff8a92abd6 #18 [ffffaad04005fee0] do_syscall_64 at ffffffff8b317159 #19 [ffffaad04005ff08] __context_tracking_enter at ffffffff8b31b6fc #20 [ffffaad04005ff18] syscall_exit_to_user_mode at ffffffff8b31b50d #21 [ffffaad04005ff28] do_syscall_64 at ffffffff8b317169 #22 [ffffaad04005ff50] entry_SYSCALL_64_after_hwframe at ffffffff8b40009b RIP: 00007f1baa5c13d7 RSP: 00007fffbcc55a98 RFLAGS: 00000202 RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f1baa5c13d7 RDX: 0000000001234567 RSI: 0000000028121969 RDI: 00000000fee1dead RBP: 00007fffbcc55ca0 R8: 0000000000000000 R9: 00007fffbcc54e90 R10: 00007fffbcc55050 R11: 0000000000000202 R12: 0000000000000005 R13: 0000000000000000 R14: 00007fffbcc55af0 R15: 0000000000000000 ORIG_RAX: 00000000000000a9 CS: 0033 SS: 002b During reboot all drivers PM shutdown callbacks are invoked. In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE. In ice_shutdown() the call chain above is executed, which at some point calls iavf_remove(). However iavf_remove() expects the VF to be in one of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If that's not the case it sleeps forever. So if iavf_shutdown() gets invoked before iavf_remove() the system will hang indefinitely because the adapter is already in state __IAVF_REMOVE. Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE, as we already went through iavf_shutdown().

Security readout for executives and security teams

Plain-English summary

Some Linux systems with Intel E810 network virtualization can hang during reboot, leaving maintenance or recovery stuck until manual intervention. The source describes an availability and reliability failure, not evidence of data theft, remote code execution, or privilege escalation.

Executive priority

Treat this as a targeted availability risk for affected network virtualization hosts. It is not currently supported as actively exploited, but a reboot hang can prolong outages during patching, incident response, or infrastructure recovery.

Technical view

The Linux iavf VF driver can sleep forever in iavf_remove during reboot when iavf_shutdown sets __IAVF_REMOVE before ice_shutdown removes VFs. The fix returns from iavf_remove when the adapter is already in __IAVF_REMOVE because shutdown already ran.

Likely exposure

Exposure appears limited to Linux hosts with Intel E810 adapters, ice, iavf, and existing SR-IOV virtual functions on affected kernel versions. Systems without this hardware and VF configuration are not indicated as exposed by the bundle.

Exploitation context

The sources describe a reboot-time driver hang. KEV is false, and the bundle provides no evidence of active exploitation, public exploit tooling, or a remote attack path. Operational impact is most plausible during planned or emergency reboots.

Researcher notes

The vulnerable condition is state-order dependent during shutdown: iavf_shutdown marks removal before ice later removes VFs, and iavf_remove waits forever outside expected states. Version metadata is present, but no CVSS, CWE, or exploitability analysis is supplied.

Mitigation direction

  • Update to a Linux kernel containing the referenced stable fixes.
  • Prioritize virtualization hosts using Intel E810 SR-IOV virtual functions.
  • Check distribution vendor advisories for packaged kernel availability.
  • Plan maintenance windows for affected host kernel updates.
  • If no vendor package is available, follow vendor guidance for interim handling.

Validation and detection

  • Inventory Linux hosts using Intel E810, ice, iavf, and SR-IOV VFs.
  • Compare running kernel versions against the affected and fixed ranges.
  • Review prior reboot incidents for hangs in iavf_remove or ice_shutdown.
  • Confirm installed kernels include the referenced stable commits or downstream backports.
  • Test reboot behavior in staging before production maintenance.
