Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via the SSHMSGCHANNELOPEN process. An attacker can cause the system to enter an infinite loop and exhaust CPU resources by advertising a zero maximum packet size during channel establishment. Remediation A fix was pushed...

CVE-2026-63835

A flaw was found in the Linux kernel's Better Approach To Mobile Ad-hoc Networking batman-adv module. When a batman-adv interface is disabled, the system can still queue network packets skbs for aggregation. These packets are not properly freed, leading to a memory leak. This can result in resour...

CVE-2026-64192

A flaw was found in the Linux kernel. When the BPF Berkeley Packet Filter Linux Security Module LSM is compiled into the kernel but not explicitly enabled at boot, a privileged user can create and update a BPF inode storage map. This improper initialization leads to an incorrect memory offset...

rabbitmq-server: RabbitMQ: Authorization bypass via regular expression injection in MQTT client ID

A flaw was found in RabbitMQ. An authenticated MQTT Message Queuing Telemetry Transport user can bypass topic-level authorization by injecting regular expression operators. This occurs because the client ID, provided by the user in the MQTT CONNECT packet, is inserted into authorization regex...

CVE-2026-47275

In nanomq versions 0.24.11 and earlier, a NULL pointer dereference in nnimqttv5msgdecodeconnect allows a malicious MQTT broker to crash any connecting NanoMQ MQTTv5 client including bridge mode with a single packet, causing remote denial of service via SIGSEGV. In nnimqttv5msgdecodeconnect...

CVE-2026-47275

Nanomq has a NULL pointer dereference in nni_mqttv5_msg_decode_connect() (mqtt_codec.c:1863) for versions ≤ 0.24.11. The code iterates CONNECT properties using prop instead of will_prop; when a packet has no connect-level properties but has will properties, dereferencing prop->next can SIGSEGV...
