{"id":"AZL-98382","summary":"CVE-2026-82327 affecting package libsolv 0.7.28-5","details":"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.","modified":"2026-09-02T14:16:18.537525043Z","published":"2026-08-28T16:18:34Z","upstream":["CVE-2026-82327"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82327"}],"affected":[{"package":{"name":"libsolv","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libsolv"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.7.28-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-98382.json"}}],"schema_version":"1.9.0"}
