A vulnerability was found in omec-project amf up to 2.1.1. This vulnerability affects unknown code of the component NGReset Message Handler. Performing a manipulation results in memory corruption. The attack is possible to be carried out remotely. The exploit has been made public and could be use...

CVE-2026-9354

A vulnerability was detected in NousResearch hermes-agent up to 2026.4.16. The affected element is an unknown function of the component Slack Agent/Mattermost Agent. The manipulation of the argument formatmessage results in escaping of output. The attack can be executed remotely. The exploit is n...

CVE-2026-46034

A flaw was found in the Linux kernel's vfio/cdx module. A local user can cause a system crash by improperly configuring Message Signaled Interrupts MSI before they are set up. This can lead to a NULL pointer dereference, resulting in a Denial of Service DoS for the system...

CVE-2026-47161 RELATE Vulnerable to Remote Code Execution (RCE) via Insecure Celery Pickle Deserialization

RELATE is a web-based courseware package. Prior to commit d66ba5659b459bf1ba56b7109b5f9ecf197cbefb, RELATE LMS configures its Celery workers to accept and deserialize untrusted 'pickle' data. An attacker who can reach the message broker can execute arbitrary commands on the host server. Combined...

JLSEC-2026-564 In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped...

In GnuPG before 2.5.17, a crafted CMS S/MIME EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can easily be leveraged for denial of service; however, there is also memory corruption that...

CVE-2026-46102

A flaw was found in the Linux kernel's network stream parser. This vulnerability occurs when the stream parser is unexpectedly stopped, such as during a message assembly timeout. A partially processed network message is not properly released from memory, leading to a memory leak. An attacker coul...
