kernel: remote DoS in TIPC kernel module

A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipclinkxmit hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization...

kernel: udp: Fix a data-race around sysctl_udp_l3mdev_accept.

In the Linux kernel, the following vulnerability has been resolved: udp: Fix a data-race around sysctludpl3mdevaccept. While reading sysctludpl3mdevaccept, it can be changed concurrently. Thus, we need to add READONCE to its reader...
