dotnet8.0-8.0.129-1.el9_8.ML.1

.NET is a managed-software framework. It implements a subset of the .NET framework APIs and several new APIs, and it includes a CLR implementation.

New versions of .NET that address a security vulnerability are now available. The updated versions are .NET SDK 8.0.129 and .NET Runtime 8.0.29.

Security Fix(es):

* dotnet: SocketsHttpHandler Http2Connection - HTTP/2 SETTINGS/PING ACK flood causing OOM (CVE-2026-50651)
