CVE-2026-57220 RabbitMQ: Stream listener does not enforce configured frame-size limit during authentication, permitting unauth'd mem-exhaust DoS

RabbitMQ is a messaging and streaming broker. Prior to 4.2.6, the RabbitMQ stream listener does not enforce the configured stream frame-size limit while assembling frames during authentication and before Tune negotiation, allowing an unauthenticated remote client to declare oversized frame length...

Name of the Vulnerable Software and Affected Versions RabbitMQ versions prior to 4.2.6 Description The RabbitMQ stream listener fails to enforce the configured stream frame-size limit when assembling frames during authentication and before Tune negotiation. This allows an unauthenticated remote...

CVE-2026-53216

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: limit XDP frame size to the RX buffer mvpp2 has short and long BM pools, and short pool buffers can be smaller than PAGESIZE. The XDP path nevertheless initializes every xdpbuff with PAGESIZE as frame size. XDP helper...

PYSEC-0000-CVE-2026-44545

daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's WebSocketServerFactory. Because Autobahn defaults both values to 0 unlimited, an unauthenticated remote attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory...

RUSTSEC-2026-0154 Unbounded 32-bit allocation

Both the SSH agent server and client accepted peer-controlled frame lengths without enforcing a maximum frame size. This could cause large memory allocations while parsing a maliciously crafted agent frame. A malicious peer could advertise an oversized frame length, causing the client or server t...

GHSA-Q6V9-R226-V65F Bandit HTTP/2 Frame Size Limit Bypass via Late Buffer Check Enables Memory Exhaustion

Summary Bandit's HTTP/2 parser checks frame size after it has already buffered the full body, instead of when it sees the 9-byte header. A peer can announce a 16 MiB frame on a connection that agreed to 16 KiB frames and the server will silently buffer up to 1024× the agreed budget per connection...

EEF-CVE-2026-42788 HTTP/2 frame size limit checked after body is buffered in bandit

Summary Allocation of Resources Without Limits or Throttling vulnerability in mtrudel bandit allows unauthenticated memory exhaustion via oversized HTTP/2 frames. 'Elixir.Bandit.HTTP2.Frame':deserialize/2 in lib/bandit/http2/frame.ex checks the SETTINGS\MAX\FRAME\SIZE limit only after...

kernel: IGB driver inadequate buffer size for frames larger than MTU

A flaw was found in igbconfigurerxring in drivers/net/ethernet/intel/igb/igbmain.c in the IGB driver in the Linux kernel. An overflow of the contents from a packet that is too large will overflow into the kernel's ring buffer, leading to a system integrity issue...

SUSE CVE-2023-45871

An issue was discovered in drivers/net/ethernet/intel/igb/igbmain.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU...

SUSE CVE-2009-4537

drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to 1 cause a denial of service temporary network outage via a packet with a crafted size, in conjunction with...

jetty: Resource exhaustion when receiving an invalid large TLS frame

When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large greater than 17408 TLS frame that is incorrectly handled, causing high CPU resources utilization. The highest threat from this vulnerability is to service availability...

PYSEC-2021-12

Eventlet is a concurrent networking library for Python. A websocket peer may exhaust memory on Eventlet side by sending very large websocket frames. Malicious peer may exhaust memory on Eventlet side by sending highly compressed data frame. A patch in version 0.31.0 restricts websocket frame to...

DEBIAN-CVE-2018-21035

In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages. Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service memory consumption...
