CVE-2026-64175
Description
A flaw was found in the Linux kernel's iwlwifi driver. When the Wi-Fi firmware crashes, the driver continues to process network transmission requests inefficiently. This creates a continuous loop of attempting to send data through an unresponsive firmware, consuming excessive CPU resources and memory. This can lead to resource exhaustion and a denial of service (DoS) for the system.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
Les mesures et les scores CVSS suivants sont préliminaires et sujets à révision.
