Summary

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.

Exploit prediction (EPSS)

0.40% probability of exploitation in the next 30 days, higher than 34% of all scored CVEs.
