How to fix?

Upgrade Minimos:latest curl-doc to version 8.21.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl-doc package and not the curl-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can continuously stream empty datagrams to indefinitely stall the client.
