      "title": "net: hinic: fix mailbox segment buffer overflow",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hinic: fix mailbox segment buffer overflow\n\ncheck_mbox_seq_id_and_seg_len() validates that seq_id does not\nexceed SEQ_ID_MAX_VAL (42) and seg_len does not exceed\nMBOX_SEG_LEN (48).  However, this allows the last segment\n(seq_id=42) to carry a full 48-byte payload, writing to offset\n42*48=2016 for 48 bytes (ending at byte 2064).  The receive\nbuffer is only MBOX_MAX_BUF_SZ (2048) bytes, resulting in a\n16-byte heap buffer overflow.\n\nThe hinic3 driver already handles this correctly by defining\nMBOX_LAST_SEG_MAX_LEN and rejecting the last segment when it\nexceeds the remaining buffer space.  Apply the same fix to the\nhinic driver.",
