Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the batman-adv module where the system could send empty VLAN responses when replying from the global TT state. This occurs because previous checks were only applied to local direct TT response code, potentially leading to inconsistent TT TLVLs (Type-Length-Value) and request storms.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
