CVE-2017-9242 is a vulnerability of currently unknown severity. The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service (system crash) via crafted system calls.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
