CVE-2026-64090

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> batman-adv: tt: avoid empty VLAN responses<br /> <br /> The commit 16116dac2339 ("batman-adv: prevent TT request storms by not<br /> sending inconsistent TT TLVLs") added checks to the local (direct) TT<br /> response code. But the response can also be done indirectly by another node<br /> using the global TT state. To avoid such inconsistency states reported in<br /> the original fix, also avoid sending empty VLANs for replies from the<br /> global TT state.
