Title
Unauthenticated TDP Function Pointer Dispatch Denial of Service in TP-Link Tapo C500
Summary
TP-Link Tapo
C500 v2.0 contains an out-of-bounds function-pointer dispatch in its TDP
(TP-Link Device Protocol) daemon. A single unauthenticated UDP datagram can
cause an invalid indirect call, crashing the main service and resulting in a
denial-of-service condition.
Successful
exploitation may allow an unauthenticated attacker with network access to the
affected UDP service to repeatedly crash the TDP daemon, disrupting normal
device operation and availability. No authentication, session establishment, or
pairing is required to trigger the condition.

Summary
An unprivileged, memory-protected ThreadX module can have the kernel read and write memory at addresses of its choosing, in privileged mode, and can use that to clear the MPU enable bit and remove its own isolation boundary.
The Module Manager decided whether a privileged service could dereference an object address a module named by asking only whether that address fell outside the module. The manager's object pool is outside every module, so the test was satisfied by an address shifted into the interior of one of the module's own privileged allocations, which denotes no object at all. The bytes such an address presents as a control block are bytes the module put there through ordinary create and set services, so the control block ID at the front of them could be made to read as any type the module chose, and the `_txe_` layer's ID test then agreed. The reported chain uses that to reach a privileged `memset` across an attacker-chosen range.

Title
Fireware OS Out-of-Bounds Read in FireCluster Sync Allows Denial of Service
Summary
An out-of-bounds read vulnerability in the FireCluster Sync processing allows an attacker positioned on the cluster interconnect, such as a compromised cluster peer or an on-path network attacker, to repeatedly crash the firewall's cluster synchronization process by sending specially crafted network traffic, resulting in a sustained denial of service.

Title
GPU DDK - OOB write in UntwiddlePOTSquare64bpp
Summary
A web page that contains unusual WebGPU content loaded into the GPU GLES render process can trigger a OOB read and/or write crash in the GPU GLES user-space shared library. On certain platforms, when the process executing graphics workload has system privileges this could enable further exploits on the device.

Title
GPU DDK - Fix for CVE-2026-49746 prevents the mapping of graphics buffers > 4GB
Summary
On GPU systems with the security vulnerability fix for CVE-2026-49746 applied, the mapping range of graphics buffers is limited which causes errors when the mapping outside of that range.
Integer truncation caused when mapping GPU buffer pages in the buffer’s range 0GB - 4GB, produces error and limits the functionality of the kernel mode driver.
Severity
No CVSS data available.

Title
Use of Out-of-range Pointer Offset in the Elasticsearch Machine Learning Native Inference Process
Summary
The native inference process that Elasticsearch uses to evaluate uploaded machine learning models accepts a model operation that computes a memory address from an offset supplied inside the model, without validating that the offset stays within the bounds of the underlying storage. A user with the privileges required to upload and deploy a trained model can craft a model that reads and writes memory outside the intended allocation. The result is heap corruption that crashes the inference process, and, with sufficient control over the heap layout, could allow arbitrary code execution in the context of that process.

Title
GPU DDK - Unvalidated sHWPerfCtlDMABuf GPU-VA, DMA-write into FW privdata via MMU ctx 0
Summary
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.

GPU DDK - Unchecked ui32TracePointer in rgxfw_log_ex()
Summary
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Out of bounds accesses triggered by malware introduced to a Guest KMD could allow privilege escalation which escapes virtualization boundaries.

CAPEC-129: Pointer Manipulation
This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
