CVE-2026-86143

In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a...

Denial Of Service (DoS)

Wire is vulnerable to Denial of Service DoS. The vulnerability is due to improper validation of negative lengths in protobuf group-skipping logic, which allows an attacker to trigger an unchecked runtime exception and crash applications processing crafted protobuf payloads...

Wire: skipGroup() missing negative-length check allows 10-byte payload to crash any Wire-decoding service

CVE-2026-45799 Maintainer summary Wire's protobuf group-skipping logic did not reject negative lengths before skipping a length-delimited field inside a group. A crafted protobuf payload could cause Wire to throw an unchecked runtime exception during decoding instead of the documented IOException...
