Description Martin Prpič 2017-03-30 10:23:22 UTC 
An integer underflow flaw was found in the way the Linux kernel handled crafted Cypress HID (Human Interface Device) reports. An attacker with physical access to the system could use this flaw to crash the system and thus cause a denial of service (DoS).
