UBUNTU-CVE-2026-52913: Null Pointer Dereference

Published Jun 24, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved: batman-adv: v: stop OGMv2 on disabled interface When a batadvhardiface is disabled, its meshiface pointer is set to NULL. However, batadvvogmsendmeshif() may still dispatch OGMs via batadvvogmqueueonif() for interfaces that have since lost their meshiface association. This results in a NULL pointer dereference when batadvvogmqueueonif() unconditionally calls netdevpriv() on the now NULL hardiface->meshiface to retrieve the batadvpriv. It is necessary to ensure that the batadvvogmqueueonif() checks that it is using the same meshiface for which batadvvogmsendmeshif() was called.

Frequently Asked Questions

What access does an attacker need to trigger this issue?

The supplied CVSS vector rates the attack as local with low privileges required and no user interaction. It is not described as remotely exploitable over the network.

Which deployments are most relevant for triage?

The vulnerable path involves BATMAN-adv OGMv2 processing and a hard interface being disabled after its mesh interface association is removed. Environments using BATMAN-adv mesh networking and performing interface disable or teardown operations are the relevant configurations.

What is the likely security impact?

The failure is a NULL pointer dereference that can cause a denial of service. The supplied vector indicates high availability impact and no confidentiality or integrity impact.

Which Ubuntu kernel package families are listed as affected?

The listed packages are linux, linux-aws, linux-aws-fips, linux-azure, linux-azure-fips, linux-gcp, linux-oracle, linux-fips, and linux-fips.
