CVE-2026-99027

Not enough EPSS history yet.

In the Linux kernel, the following vulnerability has been resolved: net: team: stop reusing skb after queue override A nonzero dev_queue_xmit() result does not return ownership of the skb. When an override port's qdisc drops it, the queue override helper used to try another port or the mode transmit op with the freed skb. Return the handoff decision separately from transmit success. Select only the first override port under RCU and stop after handing it the skb, regardless of the lower transmit result. Keep the existing success and drop accounting.
