CVE-2025-38121 Information

Jul 04, 2025 cve

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.
