What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include this patch to prevent the crash. Since this is a kernel-level issue, updating to a fixed kernel version is the recommended remediation.
Description
CVE-2024-27056 is a vulnerability in the Linux kernel's iwlwifi driver related to the management of offloading TID queues. The issue occurs because the resume code path assumes the transmission (TX) queue for the offloading TID exists and tries to synchronize the write pointer during resume. If no packets have been sent on TID 0, the queue is not allocated, causing a kernel crash. The fix ensures the queue exists at suspend time to prevent this crash.
