Overview

CVE-2026-52922 is a high-severity vulnerability. It was published on June 24, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

batman-adv: dat: handle forward allocation error

batadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb

for each DHT candidate, but does not check the return value before passing

it to batadv_send_skb_prepare_unicast_4addr(). That function dereferences

the skb unconditionally, so a failed allocation triggers a NULL pointer

dereference.

Skip forwarding to the current DHT candidate on allocation failure.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
