The issue is fixed in Linux kernel versions 6.18.34 and 7.0.11. Users and administrators should update to these or later versions to remediate the vulnerability. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's iwlwifi driver related to multi-link device (mld) handling was fixed. The issue involved dereferencing a potentially NULL pointer before checking it in the iwl_mld_remove_link function, which could lead to use-after-free conditions. The fix ensures the link pointer is freed at the end of the function after proper checks.
