    "summary": "In the Linux kernel, the following vulnerability has been resolved: net: team: free skb when broadcast has no txable port bc_transmit() sends the original skb through the last txable port. When no port is txable, it returns false without consuming the skb, but team_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the skb and its socket write-memory charge. A TX-enabled, link-down port keeps the broadcast transmit op installed. Carrier can stay up through a second link-up, TX-disabled port or be forced on by userspace. Free the original skb on the no-port path while leaving the existing drop accounting intact. Discovered by Sashiko during review of previous commit.",
