CVE-2025-54939
PoC for QUIC-LEAK CVE-2025-54939 in LSQUIC Overview This PoC highlights CVE-2025-54939, a pre-handshake memory exhaustion Denial of Service vulnerability in the LSQUIC QUIC implementation. The issue, named QUIC-LEAK, was first documented by Imperva:...
openssl: openssl: Denial of Service via excessive QUIC packet buffer retention
A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...
RockyLinux 10 : openssl (RLSA-2026:67154)
The remote RockyLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:67154 advisory. openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server CVE-2026-14456 openssl: QUIC server may trigger double free when...
Astra Linux – Vulnerability in Chromium
The use of “after free” in QUIC in Google Chrome before version 124.0.6367.60 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: Medium...
Astra Linux – Vulnerability in Firefox
Data was not properly sanitized during the decoding of a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox versions earlier than 124...
openssl: QUIC ACK-only packet retention can cause memory exhaustion
A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...
CVE-2026-78662
Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time,...
USN-8678-3: OpenSSL vulnerability
USN-8673-1 fixed vulnerabilities in OpenSSL. The update inadvertently left out the fix for CVE-2026-75803 in Ubuntu 26.04 LTS. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that OpenSSL incorrectly handled the QUIC server incoming...
CVE-2026-78966
A flaw was found in Google Chrome. An externally controlled reference within the QUIC protocol could allow a remote attacker to bypass the web origin policy. This vulnerability can be exploited by enticing a user to visit a specially crafted HTML page. The bypass of the web origin policy could le...

CVE-2026-63075
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-2026-25800
A flaw was found in Quinn, a Rust implementation of the QUIC transport protocol. A remote attacker can exploit this vulnerability by sending specially crafted QUIC stream fragments with many gaps. This can lead to high buffer overhead in the Assembler component, causing memory exhaustion and a...
