CVE-2017-9242 in Ubuntu

CVE-2017-9242

Priority

Description

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.

Ubuntu-Description

It was discovered that the IPv6 stack in the Linux kernel was performing
its over write consistency check after the data was actually overwritten. A
local attacker could exploit this flaw to cause a denial of service (system
crash).
