CVE-2026-73522 COVESA Open1722 0.9.2 Stack Buffer Overflow via avtp_to_can() in acf-can-listener

COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtptocan function increments its write...

RUSTSEC-2026-0342 Zero-length DATAGRAM frames bypass the receive buffer limit in quinn-proto

quinn-proto bounds its queue of received datagrams by charging each queued frame's payload length against TransportConfig::datagramreceivebuffersize, evicting the oldest datagrams when the limit is exceeded. A DATAGRAM frame with an empty payload was charged zero bytes, so it never triggered...

CVE-2026-73522: Stack-based Buffer Overflow

COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtptocan function increments its write...

CVE-2026-74238: Out-of-bounds Read

TIER IV Nebula through 1.2.0 contains an out-of-bounds read vulnerability in the Vlp32Decoder::unpack function that allows unauthenticated remote attackers to cause the decoder to read past the end of a received UDP buffer into adjacent heap memory by sending a short UDP datagram. Attackers can...

PT-2026-76754

Name of the Vulnerable Software and Affected Versions COVESA Open1722 versions 0.1722 through 0.9.2 Description A stack buffer overflow occurs when unauthenticated remote attackers send a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp to can function increments its write...

CVE-2026-73523: Numeric Truncation Error

COVESA Open1722 through 0.9.2 contains an integer truncation vulnerability in acf-can-listener.c that allows unauthenticated remote attackers to cause the CAN listener to transmit process stack memory onto the CAN bus by sending a rejected UDP datagram with a matching AVTP stream ID. The numcanms...

CVE-2026-74563

In the Linux kernel, the following vulnerability has been resolved: rds: tcp: hold the RCU lock across ipv6chkaddr in rdstcpladdrcheck rdstcpladdrcheck looks up a scoped IPv6 interface with devgetbyindexrcu, drops the RCU read-side lock, and only then passes the bare struct netdevice into...

GHSA-PFVM-W89X-94JW SIPSorcery: Malformed UDP datagram crashes TurnServer receive loop with no restart, disabling TURN UDP relay for all clients (DoS)

Summary TurnServer.ReceiveUdpAsync places its generic catch Exception OUTSIDE the while receive loop, and Start launches the loop fire-and-forget with no supervision or restart. A single pre-authentication UDP datagram whose STUN header first byte is in 0x80–0xFF causes STUNHeader.ParseSTUNHeader...

CVE-2026-68354

A flaw was found in the FireWire IEEE 1394 networking driver in the Linux kernel. The fragmented datagram reassembly logic in fwnetfragnew incorrectly handles list edges and merging of adjacent fragments. This can prevent complete datagrams from being recognized, potentially leading to a Denial o...

CVE-2026-68294

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...
