Overview

Affected versions of this package are vulnerable to Information Exposure due to a race condition in the tcf_pedit_offload_act_setup process. An attacker can cause heap out-of-bounds writes and potentially escalate privileges or disclose sensitive kernel memory by concurrently manipulating netlink configuration of pedit actions and cls_flower filters. This is only exploitable if the attacker has CAP_NET_ADMIN capability, which can be obtained by creating a user and network namespace.

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
