Technical description

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

wifi: iwlwifi: mld: avoid panic on init failure

In case of an error during init, in_hw_restart will be set, but it will

never get cleared.

Instead, we will retry to init again, and then we will act like we are in a

restart when we are actually not.

This causes (among others) to a NULL pointer dereference when canceling

rx_omi::finished_work, that was not even initialized, because we thought

that we are in hw_restart.

Set in_hw_restart to true only if the fw is running, then we know that

FW was loaded successfully and we are not going to the retry loop.

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.
