{"id":"AZL-110058","summary":"CVE-2026-108518 affecting package perl-DBI 1.652-1","details":"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.","modified":"2026-10-23T14:16:37.364946139Z","published":"2026-10-20T22:18:48Z","upstream":["CVE-2026-108518"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108518"}],"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-110058.json"}}],"schema_version":"1.9.0"}
