The kernel update released for Ubuntu 24.04 LTS addresses a use-after-free vulnerability in the nf_tables component.
A race condition between the vncproxy and vncwebsocket API calls in Proxmox Virtual Environment (PVE) 9.x pve-manager before 9.1.9 and 8.x before 8.4.19; qemu-server 9.x before 9.1.7 and 8.x before 8.4.7; and pve-container before 6.1.3 (PVE 9.x) and before 5.3.4 (PVE 8.x) allows an attacker with privileges to call "vncproxy" to hijack a VNC session that is established in parallel by a different user for a different VM.
CVE-2026-40952 is a privilege misconfiguration in the Secure Access installer for the Windows client and server prior to version 14.55. Attackers with local access to the client or server can use it to elevate privileges to Administrator when Secure Access is installed in a non-default location.
Heap-based buffer overflow in Windows DHCP Server allows an authorized attacker to elevate privileges over an adjacent network.
Missing authentication for critical function in Windows Server Update Service allows an authorized attacker to elevate privileges over a network.
Heap-based buffer overflow in Windows DHCP Server allows an unauthorized attacker to execute code over an adjacent network.
Incorrect implementation of authentication algorithm in Windows SMB Server allows an authorized attacker to elevate privileges over a network.
Heap-based buffer overflow in Windows DHCP Server allows an authorized attacker to execute code over a network.
A signal handler race condition in the OpenSSH server carries a risk of unauthenticated RCE as root.
CVSSv3 Score: 7.0 An out of bounds read [CWE-125] vulnerability in FortiAuthenticator may allow a remote unauthenticated attacker to retrieve sensitive information via a specially crafted request. Revised on 2026-07-14 00:00:00
CVSSv3 Score: 7.7 An Exposure of Resource to Wrong Sphere vulnerability [CWE-668] in FortiSandbox may allow an unauthenticated attacker to access the VNC server of VMs performing scanning via network requests. Revised on 2026-07-14 00:00:00
A Weak Password Recovery Mechanism for Forgotten Password exists in Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes. A remote, unauthorized attacker may assume ownership of a user’s account by manipulating this mechanism. ArcGIS Administrators should configure an email server with ArcGIS Enterprise to facilitate user self-service password recovery. The ability for an administrator to reset a user’s password remains unchanged.
