{"cve":"CVE-2026-108518","nvd":{"published":"2026-10-20T22:18:48.423","modified":"2026-10-22T17:21:57.293","status":"Awaiting Analysis","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.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-843"],"references":["https://github.com/perl5-dbi/dbi/commit/c2ff4df575d7af625bb4d0d1ef7539f90b22d8b2.patch","https://github.com/perl5-dbi/dbi/security/advisories/GHSA-7393-6f8r-fhh3","https://metacpan.org/release/HMBRAND/DBI-1.656/changes","http://www.openwall.com/lists/oss-security/2026/10/20/37"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-108518","score":0.00275,"percentile":0.19759,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
