CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the batman-adv module, specifically in the handling of TT requests, which can lead to multiple simultaneous requests being sent to an originator node. If the allocation of the send buffer fails, the current implementation incorrectly checks the return value, potentially resulting in request storms that can overwhelm the network. Organizations utilizing the Linux kernel with the batman-adv module should prioritize addressing this issue to maintain network stability and performance.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid request storms during pending request batadv_send_tt_request() allocates a tt_req_node when none exists for the destination originator node. This should prevent that a multiple TT requests are send at the same time to an originator. But if allocation of the send buffer failed, this request must be cleaned up again. But indicator for such a failure is "ret == false". But the actual implementation is checking for "ret == true". The check must be inverted to not loose the information about the TT request directly after it was attempted to be sent out. This should avoid potential request storms.
