Overview

Affected versions of this package are vulnerable to Information Exposure in the __vlan_insert_inner_tag process. An attacker can access uninitialized memory contents by transmitting specially crafted VLAN-tagged frames that exploit the lack of MAC header validation, potentially exposing sensitive kernel memory data.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
