CVE-2026-9698

A flaw was found in DBI, a Perl database interface. This vulnerability allows an attacker to trigger a buffer overflow by manipulating error messages within an application. When specific error handling options are active, an attacker can provide oversized error text, which may lead to arbitrary code execution or a denial of service (DoS).

Exploitation of this vulnerability requires that an attacker can provide values to an endpoint using perl-DBI which trigger certain errors. The attacker has no means of directly controlling the location and thus consequences of the buffer overflow, making the most likely outcome a denial-of-service due to corruption of the application's memory.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Users are advised to identify network-accessible applications which use perl-DBI and ensure that only trusted users have access to those applications.
