CVE-2026-64090 Details
Description
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid empty VLAN responses The commit 16116dac2339 ("batman-adv: prevent TT request storms by not sending inconsistent TT TLVLs") added checks to the local (direct) TT response code. But the response can also be done indirectly by another node using the global TT state. To avoid such inconsistency states reported in the original fix, also avoid sending empty VLANs for replies from the global TT state.
A vulnerability in the Linux kernel's batman-adv module has been addressed, specifically related to the handling of VLAN responses in the translation table (TT) protocol. The issue arose because the TT response could be indirectly influenced by another node's global state, leading to inconsistencies. The vulnerability is present in the Linux kernel stable tree.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed.
