CVE-2025-68353

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.7

Description The Linux kernel contains a flaw in the VXLAN implementation where a NULL pointer dereference can occur in the vxlan xmit one function. This happens because the sock4 and sock6 pointers are not guaranteed to be non-NULL, potentially leading to a kernel crash. The issue arises from lost validity checks in vxlan(6) get route after code changes in vxlan xmit one. The vulnerable function is vxlan xmit one.

Recommendations Update to version 6.7 or later.
