Technical description

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

batman-adv: dat: acquire ARP hw source only after skb realloc

The pskb_may_pull() called by batadv_get_vid() could reallocate the buffer

behind the skb. Variables which were pointing to the old buffer need to be

reassigned to avoid an use-after-free.

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.
