Official description
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix debug actions order
The order of actions taken for debug was implemented incorrectly. Now we implemented the dump split and do the FW reset only in the middle of the dump (rather than the FW killing itself on error.) As a result, some of the actions taken when applying the config will now crash the device, so we need to fix the order.
Which versions are affected by CVE-2025-38045?
It affects 1 product.
Products include Linux kernel.
How do I fix CVE-2025-38045?
Apply the vendor's patch.
