AV: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 4.13

Description The issue is related to the tpacket rcv function in the Linux kernel, which mishandles vnet headers. This might allow local users to cause a denial of service, including buffer overflow, and disk and memory corruption, or possibly have other unspecified impacts via crafted system calls.

Recommendations For Linux kernel versions prior to 4.13, update to version 4.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the tpacket rcv function to minimize the risk of exploitation.
