CVE-2023-53114: i40e: Fix kernel crash during reboot when adapter is in recovery mode

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 3cbecb1c9085a00155639404f7addbcbfc987ba3, 4ff82695266576a0b4f1077a7100b2451e476df4, 6e18f66b704bd725196508c1db93bf7338cdc8de.

Low priority for now. Upgrade to Linux Linux 3cbecb1c9085a00155639404f7addbcbfc987ba3, 4ff82695266576a0b4f1077a7100b2451e476df4, 6e18f66b704bd725196508c1db93bf7338cdc8de or later.

In the Linux kernel, the following vulnerability has been resolved: i40e: Fix kernel crash during reboot when adapter is in recovery mode If the driver detects during probe that firmware is in recovery mode then i40e_init_recovery_mode() is called and the rest of probe function is skipped including pci_set_drvdata(). Subsequent i40e_shutdown() called during shutdown/reboot dereferences NULL pointer as pci_get_drvdata() returns NULL. To fix call pci_set_drvdata() also during entering to recovery mode. Reproducer: 1) Lets have i40e NIC with firmware in recovery mode 2) Run reboot Result: [ 139.084698] i40e: Intel(R) Ethernet Connection XL710 Network Driver [ 139.090959] i40e: Copyright (c) 2013 - 2019 Intel Corporation.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
