{"id":"AZL-91713","summary":"CVE-2026-14164 affecting package libarchive for versions less than 3.7.7-7","details":"A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.","modified":"2026-09-20T05:33:47Z","published":"2026-06-30T07:16:32Z","upstream":["CVE-2026-14164"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-14164"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libarchive"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.7-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91713.json"}}],"schema_version":"1.9.0"}
