"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: ti: Fix return type of netcp_ndo_start_xmit()\n\nWith clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),\nindirect call targets are validated against the expected function\npointer prototype to make sure the call target is valid to help mitigate\nROP attacks. If they are not identical, there is a failure at run time,\nwhich manifests as either a kernel panic or thread getting killed. A\nproposed warning in clang aims to catch these at compile time, which\nreveals:\n\n drivers/net/ethernet/ti/netcp_core.c:1944:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]\n .ndo_start_xmit = netcp_ndo_start_xmit,\n ^~~~~~~~~~~~~~~~~~~~\n 1 error generated.\n\n->ndo_start_xmit() in 'struct net_device_ops' expects a return type of\n'netdev_tx_t', not 'int'. Adjust the return type of\nnetcp_ndo_start_xmit() to match the prototype's to resolve the warning\nand CFI failure."
