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.","epss":{"date":"2026-11-05","percentile":0.05496,"score":0.00163},"exploits":[],"kev":null,"metrics":[{"score":5.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793927072413,"publishedAt":1787926864777,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-82327"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2525602"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability."}],"revision":"9e3745d2ea4486c3b10618a00cf1c670596481a0c8d80f716082f677de4952ca","sources":[{"modifiedAt":1793927072413,"name":"CNA: redhat","retrievedAt":1793930945320,"url":"https://www.cve.org/CVERecord?id=CVE-2026-82327"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793930963081,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-82327"}],"ssvc":{"assessedAt":1787933267382,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Libsolv: libsolv: out-of-bounds write in repo_write() via unvalidated directory id from vertical/paged .solv filelist data","updatedAt":1793930963081}
