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...

kernel: Linux kernel: Denial of Service via malicious MTU negotiation in TIPC

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC protocol. A malicious peer can exploit this by sending a specially crafted Activate message with a very small Maximum Transmission Unit MTU value during link MTU negotiation. This can lead to an integer overflow,...

kernel: ipv6: ensure sane device mtu in tunnels

A flaw was found in the Linux kernel’s IPv6 networking code affecting the handling of IPv6 GRE tunnels. Under certain conditions, an IPv6 tunnel configuration could result in an invalid MTU Maximum Transmission Unit value being written to a network device without sanitization. Because the MTU val...
