Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS.\n\n\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109.\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.\nUsers are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.\n\n## Affected\n\n- `tomcat >= 8.5.0, <= 8.5.100`\n- `tomcat >= 9.0.0, < 9.0.110`\n- `tomcat >= 10.0.0, < 10.0.27`\n- `tomcat >= 10.1.0, < 10.1.47`\n- `tomcat >= 11.0.0, < 11.0.12`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `tomcat 11.0.12`\n\n## Vendor advisories\n\n- **RHSA-2025:19809** · Red Hat · fixed in: Red Hat JBoss Web Server 6.1 for RHEL 10, Red Hat JBoss Web Server 6.1 for RHEL 8, Red Hat JBoss Web Server 6.1 for RHEL 9 · released 2025-11-06 · [advisory](https://access.redhat.com/errata/RHSA-2025:19809)\n- **RHSA-2025:23051** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0) · released 2025-12-10 · [advisory](https://access.redhat.com/errata/RHSA-2025:23051)\n- **RHSA-2026:67163** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0) · released 2026-09-14 · [advisory](https://access.redhat.com/errata/RHSA-2026:67163)\n- **RHSA-2025:23050** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2025-12-10 · [advisory](https://access.redhat.com/errata/RHSA-2025:23050)\n- **RHSA-2026:18536** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-05-19 · [advisory](https://access.redhat.com/errata/RHSA-2026:18536)\n- **RHSA-2026:68677** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68677)\n- **RHSA-2026:68680** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.8.8), Red Hat Enterprise Linux AppStream TUS (v.8.8) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68680)\n- **RHSA-2026:68678** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.2) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68678)\n- **RHSA-2026:68679** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.4) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68679)\n- **RHSA-2026:68659** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68659)\n- **RHSA-2026:18916** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9) · released 2026-05-19 · [advisory](https://access.redhat.com/errata/RHSA-2026:18916)\n- **Red Hat VEX** · Moderate · affected: Red Hat Certificate System 10, Red Hat Data Grid 8, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Certificate System 10, Red Hat Data Grid 8, … · updated 2026-10-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-61795.json)","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
