Summary

A denial of service vulnerability exists in the Linux kernel USB driver for cypress_m8, allowing attackers with physical access to exploit specific USB devices. The flaw occurs due to the handling of USB devices that lack both an interrupt-in and an interrupt-out endpoint descriptor. Successful exploitation can lead to a NULL pointer dereference, resulting in a system crash, thereby compromising system availability. This affects Linux kernel versions prior to 4.5.1, emphasizing the need for users to update their systems to mitigate potential risks.
