This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response. In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak. ## Affected - `jetty >= 12.0.0, < 12.0.32` - `jetty >= 12.1.0, < 12.1.6` ## Remediation Upgrade past the affected range: - `jetty 12.1.6` ## Vendor advisories - **RHSA-2026:25125** · Red Hat · fixed in: Red Hat JBoss EAP 8.1 for RHEL 8, Red Hat JBoss EAP 8.1 for RHEL 9 · released 2026-06-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:25125) - **RHSA-2026:25089** · Red Hat · fixed in: HawtIO HawtIO 4.4.0 · released 2026-06-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:25089) - **RHSA-2026:60247** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.12 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60247) - **RHSA-2026:60249** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.13 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60249) - **RHSA-2026:60248** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.14 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60248) - **RHSA-2026:60239** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.15 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60239) - **RHSA-2026:60251** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.16 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60251) - **RHSA-2026:60246** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.17 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60246) - **RHSA-2026:60250** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.18 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60250) - **RHSA-2026:60252** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.19 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60252) - **RHSA-2026:60259** · Red Hat · fixed in: OpenShift Developer Tools and Services 4.20 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60259) - **Red Hat VEX** · Important · affected: OpenShift Developer Tools and Services · no fix planned: OpenShift Developer Tools and Services · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-1605.json)
