Description Vipul Nair 2026-07-28 08:27:30 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 is vulnerable to use after free in the JSON extraction function. After releasing JsonParse object memory via jsonParseFree(), the program still accesses internal member of the freed pointer, which can cause service crash and denial of service.

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