CVE-2016-9793

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.8.14

Description The issue is related to the mishandling of negative values of sk sndbuf and sk rcvbuf by the sock setsockopt function in the Linux kernel. This can be exploited by local users with the CAP NET ADMIN capability to cause a denial of service, resulting in memory corruption and system crash, by making a crafted setsockopt system call with the SO SNDBUFFORCE or SO RCVBUFFORCE option.

Recommendations For Linux kernel versions prior to 4.8.14, update to version 4.8.14 or later to resolve the issue. As a temporary workaround, consider restricting the use of the setsockopt system call with the SO SNDBUFFORCE or SO RCVBUFFORCE option to minimize the risk of exploitation.
