CVE-2026-35191

A flaw in the OpenSSL QUIC server allows a remote attacker to trigger a Denial of Service (DoS) attack via network traffic amplification. When client address validation is disabled, the QUIC stack incorrectly accounts for unvalidated credit by adding the entire datagram length for every packet co...

CVE-2026-35191 QUIC Unvalidated Amplification Credit may be Over Accounted

Issue summary: The OpenSSL QUIC server, when configured to not preform address validation, can be forced to count incoming packets multiple times in its unvalidated credit computation, leading to a violation of the RFC 9000 unvalidated connection amplification limit of 3 times the amount of data...

QUIC: Unbounded RETIRE_CONNECTION_ID Backlog

Issue summary: A malicious remote peer may flood the local QUIC stack with NEWCONNECTIONID frames by avoiding a limit check on how many connection IDs the remote QUIC stack can use. Impact summary: The local QUIC stack sends a RETIRECONNID frame for every NEWCONNECTIONID frame it receives. The...

PT-2026-102651

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description The QUIC process may retain memory for packet buffers longer than necessary. A remote peer can exploit this by sending maliciously crafted packets, forcing the local QUIC stack to keep packet...

Excessive Memory Allocation in Relative CRLDP Processing

Issue summary: A certificate with many nameRelativeToCRLIssuer CRL distribution points causes disproportionate heap growth when OpenSSL caches X.509 extensions. Impact summary: Receiving a crafted certificate from a malicious peer can lead to significant memory pressure and possible Denial of...

Potential CPU DoS via O(n^2) Fragment Reassembly in QUIC

Issue summary: The QUIC stream reassembly algorithm performance deteriorates progressively as packets are arriving out of order. The worst case has a quadratic complexity proportional to the number of stream frames kept in the buffer for the received stream data. Impact summary: A remote QUIC pee...

Timing Side-Channel in SM2 Signature Generation

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn information about the per-signature secret nonce, which over many signatures can, via a lattice / Hidd...
