**Name of the Vulnerable Software and Affected Versions** Open5GS versions up to 2.7.2 **Description** A vulnerability was found in the function `amf nsmf pdusession handle update sm context` of the file src/amf/nsmf-handler.c of the component AMF. The manipulation leads to denial of service. The attack can be launched remotely. This issue allows a single UE to crash the AMF, resulting in the complete loss of mobility and session management services and causing a network-wide outage. All registered UEs will lose connectivity, and new registrations will be blocked until the AMF is restarted, leading to a high availability impact. **Recommendations** To resolve the issue, apply a patch to fix this problem. As a temporary workaround, consider restricting access to the vulnerable function `amf nsmf pdusession handle update sm context` until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Open5GS versions up to 2.7.2 **Description** A denial of service issue has been found in the `gmm state authentication` function of the file `src/amf/gmm-sm.c` in the component AMF. This issue can be exploited remotely, leading to a network-wide outage, causing all registered UEs to lose connectivity, and blocking new registrations until the AMF is restarted. The exploit has been disclosed to the public and may be used. **Recommendations** To fix this issue, apply the patch named `e31e9965f00d9c744a7f728497cb4f3e97744ee8` to the affected Open5GS version. As a temporary workaround, consider restricting access to the `gmm state authentication` function until a patch is available.

Name of the Vulnerable Software and Affected Versions: VMware ESXi (affected versions not specified) Description: The issue is related to an out-of-bounds read, which can be triggered by a malicious actor with local administrative privileges on a virtual machine that has an existing snapshot. This can lead to a denial-of-service condition of the host. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware vCenter Server versions prior to 8.0U2d, 8.0U1e, and 7.0U3r **Description** VMware vCenter Server contains a heap-overflow vulnerability in the implementation of the DCERPC protocol. This out-of-bounds write flaw allows a malicious actor with network access to trigger the vulnerability by sending a specially crafted network packet, potentially leading to remote code execution. The vulnerability is actively being exploited in the wild, and CISA has added it to its Known Exploited Vulnerabilities Catalog. Successful exploitation can enable broad takeover and lateral movement across an organization’s virtual infrastructure. The vulnerability is rated with a CVSS score of 9.8, indicating critical severity. **Recommendations** Update VMware vCenter Server to version 8.0U2d or later. Update VMware vCenter Server to version 8.0U1e or later. Update VMware vCenter Server to version 7.0U3r or later.

**Name of the Vulnerable Software and Affected Versions** VMware vCenter Server (affected versions not specified) **Description** The issue is a heap-overflow vulnerability in the implementation of the DCERPC protocol within VMware vCenter Server. A malicious actor with network access can trigger this by sending a specially crafted network packet, potentially leading to remote code execution. The vulnerability is due to improper memory handling during the processing of DCERPC protocol requests. The DCERPC protocol is a remote procedure call mechanism used for communication between different components of the vCenter Server. Exploitation allows an unauthenticated attacker to execute arbitrary code on the server. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware ESXi, Workstation, and Fusion (affected versions not specified) **Description** The storage controllers on VMware ESXi, Workstation, and Fusion have an out-of-bounds read/write issue. A malicious actor with access to a virtual machine with storage controllers enabled may exploit this issue to create a denial of service condition or execute code on the hypervisor from a virtual machine in conjunction with other issues. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware ESXi, Workstation, and Fusion (affected versions not specified) **Description** A use-after-free vulnerability in the XHCI USB controller of VMware products allows a malicious actor with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox, whereas on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware ESXi, Workstation, and Fusion (affected versions not specified) **Description** The issue is related to an information disclosure vulnerability in the UHCI USB controller of the affected software. A malicious actor with administrative access to a virtual machine may be able to exploit this issue to leak memory from the vmx process. This vulnerability is associated with a lack of protection for service data, which could allow an attacker to disclose protected information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware Workstation and Fusion (affected versions not specified) **Description** The issue is related to an out-of-bounds read vulnerability in the USB CCID (chip card interface device) of VMware Workstation and Fusion. A malicious actor with local administrative privileges on a virtual machine may trigger an out-of-bounds read, leading to information disclosure. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
