CVE-2016-8632
Last modified
CVE-2016-8632 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
