EUVD-2026-89003
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-2026-42772 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...

CVE-2026-35191
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...

CVE-2026-35189 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...
CVE-2026-35189
A vulnerability exists in OpenSSL where a certificate containing numerous nameRelativeToCRLIssuer CRL distribution points causes disproportionate heap growth during a TLS handshake. When OpenSSL caches these X.509 extensions, it can allocate hundreds of MiB of resident memory from a certificate u...
