CVE-2025-62215_Windows_Kernel_PE
CVE-2025-62215 Exploit PoC Original code credit: https://github.com/dexterm300 🧨 Description This repository contains a proof-of-concept exploit for CVE-2025-62215 , a race condition vulnerability in the Windows kernel that can be triggered via concurrent manipulation of kernel object handles...
CVE-2026-94023
A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for using an object, and using an object a module does not own is...
CVE-2026-94023 Module delete dispatchers do not enforce kernel-object ownership before irreversible deletion
A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for using an object, and using an object a module does not own is...

CVE-2026-94023
The ThreadX operating system contains a vulnerability in the Module Manager's dispatch layer . A module can access a kernel object's delete service because the dispatcher only checks if the object lies outside the module's own code and data; however, it fails to enforce kernel-object ownership be...

CVE-2026-94192
The ThreadX kernel contains a vulnerability where a module can use txm_module_object_deallocate to return memory back to the Module Manager's object pool while the kernel is still using the associated control block. Because deallocation does not perform deletion, objects remain on active lists (s...
CVE-2026-94192 Module object deallocation can free a live ThreadX kernel object
A ThreadX module allocates the control blocks of its kernel objects from the Module Manager's object pool, and can ask for that memory back by address with txmmoduleobjectdeallocate. The manager released it whatever was in it, including a control block the kernel was still using. Deallocation is...

CVE-2026-9771
The flashcopy system call is verified by zvrfyflashcopy in drivers/flash/flashutil.c. On builds with CONFIGUSERSPACE enabled, this handler is the kernel-side trust boundary for a user-mode caller. Prior to the fix it validated only the output buffer KSYSCALLMEMORYWRITE and passed the two struct...
CVE-2026-9771 Missing device-pointer validation in flash_copy() syscall allows userspace privilege escalation

CVE-2026-12366
Zephyr's dynamic kernel-object disposal path unrefcheck in kernel/userspace/userspace.c frees an object's storage kfreedyn-data once its reference count reaches zero, after running a per-object-type cleanup. The cleanup switch handled only KOBJMSGQ and KOBJSTACK; there was no KOBJTIMER case. A...

SUSE CVE-2026-68262
In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix user array stride in pvrsetuobjarray pvrsetuobjarray copies an array of kernel objects to a userspace array whose element size is described by out-stride. When out-stride is different from the kernel object...
CVE-2026-68262
CVE-2026-68262 affects the Linux kernel’s drm/imagination: pvr_set_uobj_array() mishandles the destination user array stride when copying kernel objects to userspace. The code previously advanced the userspace pointer by the kernel object size while advancing the kernel pointer by the userspace s...

CVE-2026-10681 SMP race in `thread_idx_alloc()` lets concurrent `k_object_alloc(K_OBJ_THREAD)` callers share a kernel-object permission slot
In Zephyr's userspace dynamic-objects subsystem, threadidxalloc in kernel/userspace/userspace.c allocated a new thread permission index from the global threadidxmap bitmap without holding listslock. On SMP systems, two user-mode threads invoking the kobjectallocKOBJTHREAD syscall concurrently can...
