kernel: out-of-bounds write in qfq_change_class function

An out-of-bounds memory access flaw was found in the Linux kernel’s traffic control QoS subsystem in how a user triggers the qfqchangeclass function with an incorrect MTU value of the network device used as lmax. This flaw allows a local user to crash or potentially escalate their privileges on t...
