Description Rohit Keshri 2026-07-08 15:09:09 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme number of placeholders.

The fix for CVE-2026-10879 did not allocate enough memory to handle approximately 1.2-million placeholders.

DBI version 1.650 sets a hard limit of 99,999 placeholders.
