The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The fix released in jackson-core 2.18.6 and 2.21.1 for CVE-2026-18401 (GHSA-72hv-8253-57qq, number length     constraint bypass in the non-blocking parser) is incomplete. This record covers the remaining bypass. The     earlier fix wired validateIntegerLength() into a new _setIntLength() helper and invoked it wherever the     integer portion of a number is decided: a terminator byte arrives, a '.' or 'e'/'E' is seen, or input ends     inside a fully buffered value. It was not invoked on the attacker-relevant path where the parser runs out     of input while still inside the MINOR_NUMBER_INTEGER_DIGITS minor state and returns NOT_AVAILABLE to the     caller. As a result, an attacker who streams JSON to a non-blocking parser in many small chunks, without     ever sending a terminator byte, keeps the parser inside MINOR_NUMBER_INTEGER_DIGITS indefinitely.
    _textBuffer.expandCurrentSegment() grows the accumulator on every chunk while validateIntegerLength() is     never called. The accumulator is bounded only by maxStringLength (20 MiB by default) rather than by     maxNumberLength (1000 by default), an amplification of roughly 20,000x over the documented limit. Because     Java char values occupy two bytes, a single connection can be driven to approximately 40 MiB of heap     before the validator finally fires when the value completes. The equivalent fraction-path code is correct:
    _finishFloatFraction() calls _setFractLength() before its NOT_AVAILABLE return. The missing call affects     the integer-digit paths in _startPositiveNumber(), _startNegativeNumber() and _finishNumberIntegralPart()     in NonBlockingUtf8JsonParserBase. Impact: reactive frameworks such as Spring WebFlux/Reactor, Quarkus,     Helidon and Vert.x feed inbound HTTP or gRPC bytes to the async parser as they arrive, which is precisely     the chunked-feed shape required. Operators who set StreamReadConstraints.maxNumberLength expecting it to     cap memory per number value do not get that guarantee; memory accumulates per concurrent connection and     attacker-controlled concurrency can exhaust the JVM heap. The synchronous parsers (UTF8StreamJsonParser,     ReaderBasedJsonParser) and the async parser operating on complete input are not affected. Exploitation     requires only the ability to stream data to a parsing endpoint; no privileges or user interaction are     needed. This issue affects com.fasterxml.jackson.core:jackson-core from version 2.15.0 through 2.18.7, and     from 2.19.0 through 2.21.3, and tools.jackson.core:jackson-core from 3.0.0 through 3.1.3. Versions prior     to 2.15.0 are not affected, because StreamReadConstraints -- which defines the maxNumberLength setting --     was first introduced in jackson-core 2.15.0, so no such constraint exists to be bypassed in earlier     releases. Note that GHSA-r7wm-3cxj-wff9 states the affected 2.x range without a lower bound. The 2.22.x     and 3.2.x release lines are not affected: those branches were created after the fix commit landed on     2026-05-21 and therefore contain it from their initial releases (2.22.0, tagged 2026-06-03, and 3.2.0,     tagged 2026-06-08). (CVE-2026-68494)
