Description
A flaw was found in the Linux kernel's batman-adv (Better Approach To Mobile Ad-hoc Networking - Advanced) translation table module. This vulnerability could allow an attacker to cause network instability or a denial of service (DoS). The issue arises from the system sending inconsistent translation table type-length-value (TLVs) and empty VLAN responses, which can lead to 'TT request storms' within the network. The resolution prevents the sending of empty VLANs for replies, mitigating the risk of these inconsistencies.
