CVE-2024-27056

A vulnerability was found in the Linux kernel's iwlwifi driver for Intel wireless devices. This issue occurs when the system attempts to sync the TX queue for an offloading TID during resume, but the queue is not allocated if no packets have been sent on TID 0.

This vulnerability is rated as Moderate impact for Red Hat Enterprise Linux because it results in a local denial of service through a system crash during power-management resume operations on hardware using Intel wireless devices. Enterprise server installations and cloud instances typically do not deploy or utilize Wi-Fi interfaces, making exposure predominantly restricted to bare-metal client systems. Additionally, the flaw requires specific power state transitions rather than remote trigger mechanisms, which prevents privilege escalation or arbitrary code execution.
