Linux Kernel Vulnerability in ath6kl WiFi Driver

CVE-2025-38406

What is CVE-2025-38406?

A vulnerability exists in the Linux kernel's ath6kl WiFi driver that fails to handle improper firmware inputs appropriately. This issue arises when faulty firmware sends bad information to the driver. The previous implementation issued a warning when encountering such inputs, which did not contribute value or aid in identifying the problem source. The current fix addresses this by replacing the warning with a simpler message and providing additional context about the input sizes, improving diagnostic capabilities and enhancing system reliability.
