CVE-2016-8632

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.8.12
Description The issue is related to a heap-based buffer overflow in the Linux kernel, which can be exploited by local users to gain privileges or cause a denial of service. This is due to the tipc msg build function in net/tipc/msg.c not validating the relationship between the minimum fragment length and the maximum packet size. The exploitation of this issue is possible by leveraging the CAP NET ADMIN capability.
Recommendations For Linux kernel versions prior to 4.8.12, update to version 4.8.12 or later to resolve the issue.
