CVE-2025-26682 [HIGH] CWE-770 dotnet: .NET: ASP.NET Core denial of service with HTTP/3
dotnet: .NET: ASP.NET Core denial of service with HTTP/3
Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to deny service over a network.
A flaw was found in dotnet. Improper use of the HTTP/3 protocol allows an unauthorized remote attacker to cause an allocation of resources without limits or throttling in ASP.NET Core, resulting in a denial of service.
Statement: This issue can only be exploited when support for the HTTP/3 protocol is enabled. The .NET packages shipped in Red Hat Enterprise Linux do not support the HTTP/3 protocol. Therefore, Red Hat products are not affected by this vulnerability.
```
.NET 6.0 for RHEL-8, RHEL-9 and RHIVOS has reached its End of Life as of November 12, 2024, and is no longer supported. For additiona
