CVE-2026-68124 mctp: serial: handle zero-length frames to prevent rx buffer overflow

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

CVE-2026-68124

CVE-2026-68124 affects the Linux kernel MCTP serial driver. A zero-length frame could cause an out-of-bounds write in the receive path when rxlen == 0, requiring CAP_NET_ADMIN to attach the MCTP line discipline and bring up the netdev. The fix routes zero-length frames to STATE_TRAILER (instead o...

CVE-2026-18790 Systerel S2OPC DeleteMonitoredItemsRequest state_machine.c out-of-bounds

A weakness has been identified in Systerel S2OPC up to 1.7.3. This affects the function LockedStaMacProcessMsgDeleteMonitoredItemsResponse of the file src/ClientServer/frontend/clientwrapper/internal/statemachine.c of the component DeleteMonitoredItemsRequest Handler. This manipulation causes...

CVE-2026-18790

Systerel S2OPC up to 1.7.3 contains a vulnerability in LockedStaMac_ProcessMsg_DeleteMonitoredItemsResponse (src/ClientServer/frontend/client_wrapper/internal/state_machine.c, DeleteMonitoredItemsRequest Handler). The flaw enables an out-of-bounds read and can be exploited locally. Public exploit...

CVE-2026-59901 Netty Bzip2Decoder: Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the...

CVE-2026-59901

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to an infinite loop in the run-length encoding RLE state machine within the Bzip2Decoder handler when processing a malformed bzip2 stream, which allows an attacker to exploit the issue by sending a specially crafted bzip2 stre...

GHSA-558V-64GR-WGG4 Netty: [Bzip2Decoder] Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

The Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the event-loop thread in an infinite loop. The vulnerability exists in the run-length encoding RLE state machine within...
