In the Linux kernel, the following vulnerability has been resolved:

thunderbolt: Reject zero-length property entries in validator

tb_property_entry_valid() accepts entries with length == 0 for DIRECTORY, DATA, and TEXT types. A zero-length TEXT entry passes validation but causes an underflow in the null-termination logic:

property->value.text[property->length * 4 - 1] = '\0';

When property->length is 0 this writes to offset -1 relative to the allocation.

Reject zero-length entries early in the validator since they have no valid representation in the XDomain property protocol.
