Double Free
Overview Affected versions of this package are vulnerable to Double Free in QRX handling during channel creation failure. An attacker can trigger heap corruption and terminate the QUIC server process by sending a malformed INITIAL packet that makes portbindchannel fail after QRX allocation and...
Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling unbounded resource growth due to osslackmontxpacket in ssl/quic/quicackm.c and txppktcommit in ssl/quic/quictxp.c. A remote peer can exhaust memory by completing a QUIC handshake and...
AZL-97938 CVE-2026-63075 affecting package openssl for versions less than 3.3.7-6
Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

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...

CVE-2026-63075
OpenSSL's QUIC stack retains ACK-only packet metadata in its packet history for the full lifetime of a connection. Since ACK-only packets are not ack-eliciting, a remote peer that completes a QUIC handshake can force repeated ACK-only packet transmission (e.g., by sending numerous PING frames ) a...

CVE-2026-18798
CVE-2026-18798 is a double free (CWE-415) in the OpenSSL QUIC stack. When a QUIC server processes an INITIAL packet carrying a DCID shorter than 8 bytes , port_bind_channel() fails after enrolling the DCID and frees the QRX object. The caller port_default_packet_handler() then frees the same QRX ...
