CVE-2026-97474

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mld: purge async notifications upon nic error

This fixes a kernel panic in reconfig failure:

1. we have a BSS connection

2. we have a NAN connection

3. FW error occurs

4. reconfig restores the BSS connection

5. however, restoring the NAN connection fails due to a FW error.

6. erroneously, ieee80211_handle_reconfig_failure is called and marks all

interfaces as not-in-driver (will be fixed in a different patch).

7. mac80211 frees the links of the BSS connection but doesn't tell the

driver about that, as it thinks that this vif is not in the driver.

8. in ieee80211_stop_device, *ALL* wiphy works are getting flushed

(erroneously?)

9. Therefore, async_handlers_wk is being executed, processing the

statistics notification that was received after we restored the BSS

connection.

10. the notification handler dereferences fw_id_to_bss_conf[id], which is

now a dangling pointer, as mac80211 alre

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
