CVE-2017-9074

Assigned:2017-05-19
Published:2017-05-16
Updated:2018-01-26
Summary:The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls.
