Linux Kernel Vulnerability in WiFi Driver Functions

CVE-2026-100078

What is CVE-2026-100078?

A vulnerability has been identified in the WiFi driver iwlwifi within the Linux kernel. This issue arises from an improper argument being passed to the function iwl_mei_write_cyclic_buf(). Instead of the correct cldev argument, a q_head pointer is used, potentially leading to unexpected behavior and security implications. This flaw underscores the importance of proper function argument handling to maintain kernel integrity and security. For code references and fixes, consult the updates available in the kernel repository.
