"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: drop_monitor: fix info leak in NET_DM_ATTR_PAYLOAD\n\nnet_dm_packet_report_fill() and net_dm_hw_packet_report_fill() open code\nthe NET_DM_ATTR_PAYLOAD attribute to avoid zeroing the packet payload\nbefore overwriting it with skb_copy_bits().\n\nskb_put() reserves nla_total_size(payload_len), i.e. the header plus the\nNLA_ALIGN() padding, but only payload_len bytes are copied in. When\npayload_len is not a multiple of 4 the 1-3 padding bytes are never\ninitialized and are leaked to user space inside the netlink message.\n\nKMSAN confirms the leak for the software path when the packet payload\nlength is not 4-byte aligned:\n\n BUG: KMSAN: kernel-infoleak in _copy_to_iter\n _copy_to_iter\n __skb_datagram_iter\n skb_copy_datagram_iter\n netlink_recvmsg\n sock_recvmsg\n __sys_recvfrom\n Uninit was created at:\n kmem_cache_alloc_node_noprof\n __alloc_skb\n net_dm_packet_work\n Bytes 173-175 of 176 are uninitialized\n\nUse __nla_reserve(), which sets up the attribute header and zeroes the\npadding, instead of open coding the attribute construction."
