Last modified

CVE-2017-6074 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to obtain root privileges or cause a denial of service (double free) via an application that makes an IPV6_RECVPKTINFO setsockopt system call.. EPSS estimates a 5.96% chance of exploitation in the next 30 days.
