  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: check iparea_offset and ipv6_prefixes_cnt when receiving proposal msg\n\nWhen receiving proposal msg in server, the field iparea_offset\nand the field ipv6_prefixes_cnt in proposal msg are from the\nremote client and can not be fully trusted. Especially the\nfield iparea_offset, once exceed the max value, there has the\nchance to access wrong address, and crash may happen.\n\nThis patch checks iparea_offset and ipv6_prefixes_cnt before using them.",
