DescriptionCVE.org

A flaw was found in libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with .solv repository cache files. 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.

AnalysisAI

Out-of-bounds memory write in libsolv crashes RPM-based package manager tools (dnf, yum, zypper) when processing a corrupted or specially crafted .solv repository cache file. The root cause is an absent array-index bounds check on directory-id values read from compressed filelist data during .solv file rewriting - but because the out-of-bounds write stores only a fixed, non-attacker-controlled value, the vendor explicitly rules out arbitrary code execution, confining impact to denial of service. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that a .solv repository cache file with an out-of-range directory-id in its compressed filelist section exists on the local filesystem in a path processed by dnf, yum, or zypper. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor-assigned CVSS 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) reflects a moderate, local denial-of-service vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the libsolv update released by Red Hat for affected RHEL 7, 8, 9, and 10 platforms once available; monitor https://access.redhat.com/security/cve/CVE-2026-82327 for the exact patched package version, which is not independently confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report.
