In versions 0.11.5 and below, and 0.12.0,  decompressing invalid LZ4 data can leak sensitive information from uninitialized memory or from previous decompression operations. The library fails to properly validate offset values during LZ4 \"match copy operations,\" allowing out-of-bounds reads from the output buffer. The block-based API functions (`decompress_into`, `decompress_into_with_dict`, and others when `safe-decode` is disabled) are affected, while all frame APIs are unaffected. The impact is potential exposure of sensitive data and secrets through crafted or malformed LZ4 input. This issue has been fixed in versions 0.11.6 and 0.12.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.2,"severity":null}],"references":["https://github.com/PSeitz/lz4_flex/security/advisories/GHSA-vvp9-7p8x-rfvv","https://github.com/PSeitz/lz4_flex/commit/055502ee5d297ecd6bf448ac91c055c7f6df9b6d","https://rustsec.org/advisories/RUSTSEC-2026-0041.html"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-13426","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Mar 20, 2026, 12:49:12 AM","dateUpdated":"Sep 17, 2026, 12:04:33 PM"},"relatedAdvisories":[{"id":"RHSA-2026:11800","title":"Red Hat Security Advisory: Logging for Red Hat OpenShift - 6.2.10","vulnerabilityIds":["CVE-2026-25679","CVE-2026-27137","CVE-2026-32829"]},{"id":"RHSA-2026:22862","title":"Red Hat Security Advisory: Logging for Red Hat OpenShift - 6.4.5","vulnerabilityIds":["CVE-2026-25679","CVE-2026-27137","CVE-2026-31812","CVE-2026-32280","CVE-2026-32281","CVE-2026-32282","CVE-2026-32829","CVE-2026-33810"]},{"id":"RHSA-2026:16354","title":"Red Hat Security Advisory: Logging for Red Hat OpenShift - 6.5.1","vulnerabilityIds":["CVE-2026-32829"]},{"id":"WID-SEC-W-2026-1504","title":"Logging Subsystem for Red Hat OpenShift: Schwachstelle ermöglicht Offenlegung von Informationen","vulnerabilityIds":["CVE-2026-32829"]},{"id":"RHSA-2026:19712","title":"Red Hat Security Advisory: RHOAI 3.3.3 - Red Hat OpenShift AI","vulnerabilityIds":["CVE-2025-6242","CVE-2025-12816","CVE-2025-13465","CVE-2025-15284","CVE-2025-59057","CVE-2025-61726","CVE-2025-61729","CVE-2025-62164","CVE-2025-62718","CVE-2025-64756","CVE-2025-66031","CVE-2025-66418","CVE-2025-66448","CVE-2025-66471","CVE-2025-69223","CVE-2025-69873","CVE-2026-0846","CVE-2026-0847","CVE-2026-4800","CVE-2026-21441","CVE-2026-21884","CVE-2026-22029","CVE-2026-22778","CVE-2026-23490","CVE-2026-23745","CVE-2026-24049","CVE-2026-24486","CVE-2026-24779","CVE-2026-25639","CVE-2026-25990","CVE-2026-27893","CVE-2026-28684","CVE-2026-29063","CVE-2026-29074","CVE-2026-30922","CVE-2026-31812","CVE-2026-32597","CVE-2026-32829","CVE-2026-32981","CVE-2026-33186","CVE-2026-33231","CVE-2026-33236","CVE-2026-34986","CVE-2026-40175","CVE-2026-40192","CVE-2026-40895"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
