Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

CVE-2026-68432 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.10.265, 5.15.216, 6.1.183, 6.6.148, 6.12.101, 6.18.42, 7.1.6 or higher.
Overview
Affected versions of this package are vulnerable to Improper Input Validation in the vxlan_changelink process. An attacker can gain unauthorized access to and manipulate network tunnel configurations by issuing a netlink changelink request from a user namespace with CAP_NET_ADMIN in the device's network namespace but without equivalent privileges in the underlay network namespace. This allows exposure of encapsulated traffic, redirection or injection of overlay traffic, and disruption of network connectivity for affected services.
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
