  "summary": "thunderbolt: Reject zero-length property entries in validator",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Reject zero-length property entries in validator\n\ntb_property_entry_valid() accepts entries with length == 0 for\nDIRECTORY, DATA, and TEXT types.  A zero-length TEXT entry passes\nvalidation but causes an underflow in the null-termination logic:\n\n  property->value.text[property->length * 4 - 1] = '\\0';\n\nWhen property->length is 0 this writes to offset -1 relative to\nthe allocation.\n\nReject zero-length entries early in the validator since they have no\nvalid representation in the XDomain property protocol.",
