Description Charles Timko 2026-07-16 19:21:54 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.

Access of resource using incompatible type ('type confusion') in .NET Core allows an unauthorized attacker to deny service over a network.

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