CVE-2026-64487

A flaw was found in the Linux kernel's sound subsystem, specifically within the ALSA caiaq driver responsible for handling Traktor Kontrol S4 devices. A local attacker, by providing specially crafted input from a connected device, could exploit an out-of-bounds read vulnerability. This issue arises from incorrect handling of input stream lengths, leading to the system reading beyond its allocated memory buffer. Successful exploitation could result in the disclosure of sensitive information from kernel memory or cause a system crash, leading to a denial of service.
