What the CVE records say

CVE-2023-52522 — In the Linux kernel, the following vulnerability has been resolved: net: fix possible store tearing in neigh_periodic_work() While looking at a related syzbot report involving neigh_periodic_work(), I found that I forgot to add an annotation when deleting an RCU protected item from a list. Readers use rcu_deference(*np), we need to use either rcu_assign_pointer() or WRITE_ONCE() on writer side to prevent store tearing. I use rcu_assign_pointer() to have lockdep support, this was the choice made in neigh_flush_dev().

Impact

Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data or Denial of Service (DoS).

What to do

  1. Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
  2. If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
  3. If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
  4. Harden in parallel: security hardening baseline and ransomware protection on ONTAP.
