A fix is available — apply it.

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

wifi: iwlwifi: mld: don't dereference a pointer before NULL checking it

In iwl_mld_remove_link, the link->fw_id is saved at the beginning of the function so we have it after we freed the link.

But the link pointer can be NULL, and is not checked when the fw_id is stored.

Fix it by simply freeing the link at the end of the function.

fFixes: 0e66a39f4f0e ("wifi: iwlwifi: fix potential use after free in iwl_mld_remove_link()")
