In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Check for invalid/obsolete root *after* making MMU pages available Check for a "stale" page fault, i.e. for an invalid and/or obsolete root, after making MMU pages available for the shadow MMU. If reclaiming shadow pages zaps an in-use root, i.e. marks it invalid, then KVM will attempt to map memory into an invalid root. On its own, populating an invalid root is "fine", but because child shadow pages inherit their parent's role, any children created during the map/fetch will be created as invalid pages, thus violating KVM's invariant that invalid pages are never on the list of active MMU pages. Note, the underlying flaw has existed since KVM first started tracking invalid roots in 2008 (commit 2e53d63acba7, "KVM: MMU: ignore zapped root pagetables"), but the true badness only came along in 2020 (Linux 5.9) with the invariant that invalid shadow pages can't be on the list of active pages. Note #2, inheriting role.invalid when creating child shadow pages is also far from ideal; that flaw will be addressed separately.

A cryptographic weakness exists in affected Omada devices where site credentials are protected using a legacy hashing algorithm that does not provide sufficient protection. An attacker who obtains access to stored credential data may be able to recover valid credentials to gain unauthorized access to affected devices or management environments.

A cryptographic weakness exists in the Omada adoption protocol.  The protocol relies on hard-coded cryptographic keys to establish trust and protect authentication exchanges between controllers and managed devices during device adoption. An attacker may be able to impersonate trusted controllers or managed devices and gain access to sensitive adoption-related communications.

A cryptographic weakness exists in the Omada device adoption process.  During adoption, authentication credentials associated with site management are transmitted using a weak hashing algorithm that does not provide sufficient protection. An attacker who successfully intercepts adoption-related authentication traffic may be able to recover valid credentials and gain unauthorized access to managed devices or controller-managed environments.

An incomplete patch for CVE-2026-18556 allows for authentication bypass and account takeover in N-central Versions through 2026.3.1

Authentication bypass using an alternate path or channel vulnerability in N-able N-central allows Authentication Bypass. This issue affects N-central: through 2026.1.

Improper preservation of SQL mode when renaming databases in cPanel allows execution of SQL in root context.

HTTP Smuggling in cPanel allows potential leak of credentials.

The RCU II+ and Multiload II+ are vulnerable to an unauthenticated service that exposes a debug interface granting full root-level access to the embedded system. This vulnerability stems from a network-accessible port running a Target Communications Framework (TCF) service that does not require any authentication, allowing an attacker to directly interact with the Linux environment that powers the device. Once connected, an attacker can freely view and modify the filesystem, manipulate running processes, and control network interfaces, enabling deep alteration of system behavior.

Action Pack is a framework for handling and responding to web requests. In versions prior to 7.2.3.2, 8.0.5.1 and 8.1.3.1, Active Storage does not disable libvips operations marked unsafe for untrusted content, allowing a crafted upload to invoke such an operation. Consuming applications are affected when configured to use libvips and accept image uploads from untrusted users. An unauthenticated attacker may exploit this behavior to read arbitrary files accessible to the Rails process, including environment variables and application secrets. Exposure of credentials such as secret_key_base or external-service tokens may enable remote code execution or lateral movement. This issue has been fixed in versions 7.2.3.2, 8.0.5.1 and 8.1.3.1.

SolarWinds Web Help Desk is found to be affected by a SAML authentication bypass vulnerability. This requires the SAML 2.0 authentication method to be enabled.

VMware ESX contains an insufficient logging vulnerability. A malicious administrator could exploit this issue to perform certain operations without them being logged.

VMware vCenter contains a directory traversal vulnerability in the Syslog server. A malicious actor with network access to vCenter may exploit this issue to execute arbitrary code.

VMware vCenter contains an authentication bypass vulnerability in the VMware Directory Service. A malicious actor with network access to vCenter may exploit this issue to bypass authentication and gain unauthorized access to the system.

VMware ESX contains an out-of-bounds write vulnerability in the VMXNET3 virtual network adapter. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Non VMXNET3 virtual adapters are not affected by this issue.

VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and Fusion, the impact of this vulnerability is restricted to information disclosure.

Improper Enforcement of Message Integrity During Transmission in a Communication Channel vulnerability in Mitsubishi Electric MELSEC MX Controller MX-R model, MELSEC MX Controller MX-F model, Master/local module, CC-Link IE TSN interface board, Motion module, MELSEC iQ-L Series Motion Module, Motion Control Board, Block-type remote module, Block-type remote module with safety functions, Analog-Digital converter module, Digital-Analog converter module, CC-Link IE TSN compatible coupler, FPGA module, Tension meter, AC Servo MELSERVO-J5, AC Servo MELSERVO-JET, Liner Track System MTR-S series Linear track control module, Inverter FR-A800/F800/E800 Series, Industrial Robot CR800-D series controller Network Base Card, CC-Link IE TSN expansion unit, CC-Link IE TSN-CC-Link IE Field Network bridge module, CC-Link IE TSN-AnyWireASLINK bridge module, Energy Measuring Unit CC-Link IE TSN Communication Unit, GOT3000 Series, CC-Link IE TSN Communication Unit, Motion Control Software, CC-Link IE TSN Communication Software for Windows, Analysis Support Software MELSOFT VIMA, Master/Local module Designated communication LSI DeviceKit, Remote Station Communication LSI with GbE-PHY, CC-Link IE TSN Master/Local module Designated communication LSI SDK, and Remote station software development kit allows an attacker with access to a CC-Link IE TSN network to tamper with communication data (control input/output values) by sending specially crafted packets under specific timing conditions. This could allow the attacker to cause a denial-of-service (DoS) condition in the affected product by interfering with its control function or causing it to operate incorrectly.

Adobe Campaign Classic (ACC) is affected by an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to gain file system read access. Exploitation of this issue does not require user interaction. Scope is changed.

Adobe Campaign Classic (ACC) is affected by an Incorrect Authorization vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.

A vulnerability in the web interface of Cisco Secure Firewall Management Center (FMC) Software could allow an unauthenticated, remote attacker to log in to an affected device using a low-privileged account to access sensitive data within the impacted systems. This vulnerability is due to the presence of static user credentials for a low-privileged account. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user.  Note: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced.   Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates. The reason is that this vulnerability can be used with other Cisco Secure FMC Software vulnerabilities to elevate privileges.
