Astra Linux – vulnerability in linux-6.12

In the Linux kernel, the following vulnerability has been resolved: xsk: validate MTU against usable frame size on bind The AFXDP bind currently accepts zero-copy pool configurations without verifying that the device MTU fits within the usable frame space provided by the UMEM chunk. This becomes...

CVE-2026-98582

In the Linux kernel, the following vulnerability has been resolved: nfc: st21nfca: validate received frame size st21nfcahcii2crepack trims a received frame at its EOF marker before removing byte stuffing. It then assumes the truncated frame contains the LLC header and two CRC bytes, and it...

GHSA-XWWF-M8FG-P9Q2 RabbitMQ amqp091-go: Denial of Service via Sub-Spec Frame Size Negotiation

Summary A Denial of Service DoS vulnerability exists in the AMQP client's connection negotiation logic. The AMQP specification explicitly mandates a strict minimum frame size of 4096 bytes to prevent pathological packet fragmentation. While the library defines a frameMinSize = 4096 constant, the...

CVE-2026-77403

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. A malicious or compromised AMQP broker can exploit this by advertising an extremely small frame size during connection negotiation. This can lead to excessive fragmentation of client publications, consuming significant CPU resources...

CVE-2026-75516 RabbitMQ Java client: Frame-level OOM: Math.min(maxInboundMessageBodySize, 0) defeats frame size enforcement

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.34.0, AMQConnection.start applies Math.minmaxInboundMessageBodySize, frameMax after Connection.Tune negotiation even though AMQP defines frameMax value zero as...

GHSA-GQ9P-F254-H286 Http4s: Ember HTTP/2 buffers a frame's declared payload before checking SETTINGS_MAX_FRAME_SIZE

Summary An unauthenticated peer can make Ember's HTTP/2 read loop hold 16 MiB of a single frame in memory on a connection where Ember advertised a 16 KiB limit. The declared length is readable from the frame's first 9 bytes, but it is not compared against SETTINGSMAXFRAMESIZE until the whole...

CVE-2026-88975

Http4s (a Scala HTTP library) is vulnerable in Ember's HTTP/2 read loop prior to versions 0.23.37 and 1.0.0-M48 . The loop parses a frame's 24-bit declared length but buffers the entire payload before comparing it against SETTINGS_MAX_FRAME_SIZE . An unauthenticated peer can declare a payload nea...
