Linux Distros Unpatched Vulnerability : CVE-2026-68496

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The Smile parser in FasterXML jackson-dataformats-binary never invokes StreamReadConstraints.validateNameLength when decoding JSON object property names, so the...

CVE-2026-68496

The Smile parser in FasterXML jackson-dataformats-binary never invokes StreamReadConstraints.validateNameLength when decoding JSON object property names, so the maxNameLength limit is not enforced for this format. SmileParser.handleLongFieldName grows its internal name buffer through an...

CVE-2026-68496

The Smile parser in FasterXML jackson-dataformats-binary fails to invoke StreamReadConstraints.validateNameLength() when decoding JSON object property names. This allows an attacker to provide a Smile document with a property name of unbounded length , causing SmileParser._handleLongFieldName() t...

CVE-2026-89425

A flaw was found in FasterXML jackson-core. This vulnerability allows a remote attacker to cause a Denial of Service DoS by providing a specially crafted, malformed token to the JsonFactory.createParserDataInput method. The UTF8DataInputJsonParser component, responsible for handling DataInput...

CVE-2026-91777

Forward-reference completion for @JsonIdentityInfo object IDs in FasterXML jackson-databind performs a linear scan of the pending-reference accumulator for every resolved ID. The affected paths are CollectionDeserializer.CollectionReferringAccumulator.resolveForwardReference and the equivalent...

CVE-2026-91776

TypeDeserializerBase.findDeserializer in FasterXML jackson-databind caches the resolved deserializer under the raw, attacker-supplied type ID. When name-based polymorphism is configured with a fallback, for example @JsonTypeInfouse = Id.NAME, defaultImpl = ..., every distinct unrecognized type ID...
