Description Vipul Nair 2026-07-28 08:37:21 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.

SQLite 3.41 has a use-after-free vulnerability in jsonRemoveFunc of SQLite JSON module. The parsed JSON object is freed at line 3555, while line 3575 still calls jsonLookupStep with the released pointer. Remote attackers can exploit this flaw to crash the service and leak heap memory information.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
