What to do
AI-suggested
A fix has been implemented in the Linux kernel to prevent the queuing of packets on disabled interfaces in the batman-adv module. Users should apply the official Linux kernel updates that include this patch once available.
Description
A vulnerability in the Linux kernel's batman-adv module could lead to a memory leak when an interface is disabled. Specifically, the system fails to block new packet queues on a disabled interface, causing queued packets to never be freed or processed.
