      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/ipv6: ioam6: prevent schema length wraparound in trace fill\n\nioam6_fill_trace_data() stores the schema contribution to the trace\nlength in a u8. With bit 22 enabled and the largest schema payload,\nsclen becomes 1 + 1020 / 4, wraps from 256 to 0, and bypasses the\nremaining-space check. __ioam6_fill_trace_data() then positions the\nwrite cursor without reserving the schema area but still copies the\n4-byte schema header and the full schema payload, overrunning the trace\nbuffer.\n\nKeep sclen in an unsigned int so the remaining-space check and the write\ncursor calculation both see the full schema length.",
