Issue summary: A non-constant-time optimized implementation of scalar point multiplication is used for SM2 private key operations on ARM64 and RISC-V platforms. Impact summary: An attacker able to measure the time taken by, or to observe the cache-line access pattern of SM2 signing or decryption ...

EUVD-2026-89005

Issue summary: QUIC process may keep memory for QUIC packet buffer for much longer period than necessary. Impact summary: Remote peer can exploit this vulnerability by sending maliciously crafted packets, making the local QUIC stack to keep the memory for packet buffers allocated. The time for...

CVE-2026-42772 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...

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...

CVE-2026-42772

A flaw in OpenSSL allows a remote attacker to cause a Denial of Service (DoS) by exploiting an inefficient QUIC stream reassembly algorithm. When packets arrive out of order, the software falls back to a head-to-tail linear search for fragments in a doubly-linked list. By manipulating sequence of...

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...

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...
