HIGHCVSS 7.8/10EPSS 0.42%

Last modified

CVE-2017-9074 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
