Package : haproxy
CVE ID : CVE-2026-26081
Asim Viladi Oglu Manizada reported that HAProxy, a load balancing
reverse proxy, does not properly validate an INITIAL QUIC packet with
specially crafted data, which may result in denial of service (process
crash).
For the stable distribution (trixie), this problem has been fixed in
version 3.0.11-1+deb13u2.
We recommend that you upgrade your haproxy packages.
