{"id":"CVE-2026-108518","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-108518","generatedAt":"2026-10-28T00:59:57.297Z","title":"DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element.","description":"DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element.\n\nAn {attr} element names a database handle attribute, which dbi_profile reads from the handle's inner hash. It expects the inner handle as a reference and dereferences it, but a handle that is being destroyed hands back the inner hash itself, so the dereference yields the hash's bucket array. A type check on that pointer usually fails and the call goes unprofiled. When the memory it addresses passes the check, the attribute lookup dereferences a NULL or invalid pointer and the process dies on SIGSEGV.\n\nThe Path is set by the application, by the Profile handle attribute, or by the DBI_PROFILE environment variable, so `DBI_PROFILE={ImplementorClass}` can crash an unmodified program.","published":"2026-10-20T22:18:48.000Z","lastModified":"2026-10-22T17:21:57.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":null,"cwe":["CWE-843"],"affected":[],"epss":{"score":0.00275,"percentile":0.19774,"date":"2026-10-26","history":[{"date":"2026-10-21","score":0.00229,"percentile":0.12878}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
