AZL-105458 CVE-2026-75804 affecting package cloud-hypervisor 52.0.152-1

Issue summary: OpenSSL QUIC stack does not enforce connection level flow control for streams. Remote peers may send more bytes as long as they fit within the stream flow control limits. Impact summary: A malicious remote peer may exploit the lack of connection flow control for streams to make the...

SUSE CVE-2026-18798

Issue summary: QUIC server may double free QRX QUIC record layer RX object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence...

SUSE CVE-2026-14456

Issue summary: When an OpenSSL QUIC server Listener SSL object processes valid QUIC Initial packets for unknown destination connection IDs, it can allocate and queue new incoming channels without enforcing any limit. Impact summary: A remote peer that can make many Initial packets reach the serve...
