{"schemaVersion":3,"id":"CVE-2026-108518","aliases":["DEBIAN-CVE-2026-108518"],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-20T21:23:13.373Z","modified":"2026-10-21T00:17:16.110Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":0.00229,"percentile":0.12878,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-21T00:00:00.000Z","score":0.00229,"percentile":0.12878}],"last30":[{"date":"2026-10-21T00:00:00.000Z","score":0.00229,"percentile":0.12878}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type ('Type Confusion')","description":"The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/843.html"}],"affected":[{"vendor":"debian","product":"libdbi-perl","name":"libdbi-perl","label":"libdbi-perl","ecosystem":"Debian","cpePart":null,"purl":"pkg:deb/debian/libdbi-perl","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://security-tracker.debian.org/tracker/CVE-2026-108518","label":"security-tracker.debian.org/tracker/CVE-2026-108518","hostname":"security-tracker.debian.org","tags":["Advisory"]},{"url":"https://github.com/perl5-dbi/dbi/security/advisories/GHSA-7393-6f8r-fhh3","label":"github.com/perl5-dbi/dbi/security/advisories/GHSA-7393-6f8r-fhh3","hostname":"github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/perl5-dbi/dbi/commit/c2ff4df575d7af625bb4d0d1ef7539f90b22d8b2.patch","label":"github.com/perl5-dbi/dbi/commit/c2ff4df575d7af625bb4d0d1ef7539f90b22d8b2.patch","hostname":"github.com","tags":["Patch"]},{"url":"https://metacpan.org/release/HMBRAND/DBI-1.656/changes","label":"metacpan.org/release/HMBRAND/DBI-1.656/changes","hostname":"metacpan.org","tags":["Release Notes"]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/20/37","label":"www.openwall.com/lists/oss-security/2026/10/20/37","hostname":"www.openwall.com","tags":[]}],"lineage":{"upstream":[],"downstream":["OPENSUSE-SU-2026:12201-1"],"duplicates":[],"related":["OPENSUSE-SU-2026:12201-1"]},"timeline":[{"kind":"published","date":"2026-10-20T21:23:13.373Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-21T00:17:16.110Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T12:13:45.928Z","stale":false,"partial":false}}
