Description
The issue is related to the HTTP/3 QUIC module in NGINX Plus and NGINX OSS.

The vulnerability is also described as a buffer overflow in memory, which can be exploited by a remote attacker using specially crafted HTTP/3 requests to cause a denial of service.
Recommendations
For NGINX Plus, consider disabling the HTTP/3 QUIC module until a patch is available.
