When libsolv rewrites a .solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted .solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it. Successful exploitation is expected to result in a crash of the affected tool (denial of service); it is not expected to allow arbitrary code execution because the out-of-bounds write always stores a fixed, non-attacker-controlled value." } ], "affected": [ { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 10", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:10" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 7", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:7" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:8" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:9" ] }, { "vendor": "Red Hat", "product": "Red Hat Hardened Images", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:hummingbird:1" ] }, { "vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "openshift/ose-rhel-coreos-8", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:openshift:4" ] }, { "vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "openshift/ose-rhel-coreos-9", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:openshift:4" ] }, { "vendor": "Red Hat", "product": "Red Hat Satellite 6", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:satellite:6" ] }, { "vendor": "Red Hat", "product": "Red Hat Satellite 6", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv0", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:satellite:6" ] }, { "vendor": "Red Hat", "product": "Red Hat Satellite 6", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "python3.12-solv", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:satellite:6" ] }, { "vendor": "Red Hat", "product": "Red Hat Satellite 6", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "python-solv", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:satellite:6" ] }, { "vendor": "Red Hat", "product": "Red Hat Update Infrastructure 4 for Cloud Providers", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "libsolv", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:rhui:4::el8" ] } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2026-82327", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2525602", "name": "RHBZ#2525602", "tags": [ "issue-tracking", "x_refsource_REDHAT" ] } ], "datePublic": "2026-08-28T14:00:00.000Z", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-129", "description": "Improper Validation of Array Index", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-129: Improper Validation of Array Index", "workarounds": [ { "lang": "en", "value": "No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability." } ], "timeline": [ { "lang": "en", "time": "2026-08-26T15:19:36.000Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2026-08-28T14:00:00.000Z", "value": "Made public." } ], "credits": [ { "lang": "en", "value": "Red Hat would like to thank Dinko Georgiev (StorPool) for reporting this issue." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-10-21T20:06:20.412Z" }, "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-08-28T16:07:47.382953Z", "id": "CVE-2026-82327", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-08-28T16:08:04.589Z" } } ] } }
