CVE-2025-68182

A use-after-free was found in the Intel iwlwifi driver in the Linux kernel. The iwl_mld_remove_link() function frees a link structure via kfree_rcu() but then dereferences it to read fw_id. Since RCU freeing is asynchronous, this creates a potential use-after-free window.

Intel WiFi adapters using the iwlwifi driver are affected. The race window is small since kfree_rcu deferral provides some protection, but the code is nonetheless incorrect and could cause issues under memory pressure.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the iwlwifi module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
