Hello: This patch was applied to netdev/net.git (main) by Paolo Abeni [off-list ref]: On Tue, 30 Jun 2026 10:41:09 -0700 you wrote:
When ingress deaggregation is disabled, rmnet_map_ingress_handler() passes the skb straight to __rmnet_map_ingress_handler(), skipping the length validation that rmnet_map_deaggregate() performs on the aggregated path. The parser then dereferences the MAP header and csum header/trailer based on the on-wire pkt_len without checking skb->len, so a short frame is read out of bounds: [...]
