{"id":"AZL-105215","summary":"CVE-2026-88816 affecting package perl-DBI 1.652-1","details":"DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName.\n\nfetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to an integer (IV) or floating-point (NV) value, that pointer is invalid, so reading the key name triggers a segmentation fault.\n\nThis can be triggered with the following code:\n\n   my $dbh = DBI-\u003econnect( \"dbi:ExampleP:\", \"\", \"\",\n       { RaiseError =\u003e 0, PrintError =\u003e 0 } );\n   $dbh-\u003e{FetchHashKeyName} = 42;\n\n   my $sth = $dbh-\u003eprepare(\"select mode, size, name from .\");\n   $sth-\u003eexecute;\n   $sth-\u003efetchrow_hashref;","modified":"2026-10-03T05:35:10Z","published":"2026-09-28T17:17:52Z","upstream":["CVE-2026-88816"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88816"}],"affected":[{"package":{"name":"perl-DBI","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/perl-DBI"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.652-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105215.json"}}],"schema_version":"1.9.0"}
