** Description changed: - ipv4: Missing sk_nulls_node_init() in ping_unhash() allows local kernel - privileges escalation via use-after-free. + The ping_unhash function in net/ipv4/ping.c in the Linux kernel before + 4.0.3 does not initialize a certain list data structure during an unhash + operation, which allows local users to gain privileges or cause a denial + of service (use-after-free and system crash) by leveraging the ability + to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or + IPPROTO_ICMPV6 protocol, and then making a connect system call after a + disconnect. Break-Fix: c319b4d76b9e583a5d88d6bf190e079c4e43213d a134f083e79fb4c3d0a925691e732c56911b4326
