  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: team: free skb when broadcast has no txable port\n\nbc_transmit() sends the original skb through the last txable port.\nWhen no port is txable, it returns false without consuming the skb, but\nteam_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the\nskb and its socket write-memory charge.\n\nA TX-enabled, link-down port keeps the broadcast transmit op installed.\nCarrier can stay up through a second link-up, TX-disabled port or be\nforced on by userspace. Free the original skb on the no-port path while\nleaving the existing drop accounting intact.\n\nDiscovered by Sashiko during review of previous commit.",
