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

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-2026-12366

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...

CVE-2026-12366 Use-after-free freeing an armed dynamically-allocated k_timer in Zephyr userspace object disposal

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

CVE-2026-10681 overview (Zephyr) : In the userspace dynamic-objects subsystem, thread_idx_alloc() reads and clears the global _thread_idx_map[] bitmap without holding lists_lock. On SMP systems, concurrent k_object_alloc(K_OBJ_THREAD) calls can observe the same free bit, perform a non-atomic RMW,...

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...

CVE-2026-64033

CVE-2026-64033 describes a use-after-free in Linux kernel RDMA/rtrs path file cleanup. In rtrs_srv_create_path_files(), if an error occurs after sysfs root folders were created and srv_path->kobj initialized, cleanup calls kobject_put(&srv_path->kobj) before rtrs_srv_destroy_once_sysfs_root...

CVE-2026-10670 User-triggerable kernel NULL-pointer dereference (DoS) in `k_thread_name_copy()` syscall verifier

The CONFIGUSERSPACE verification handler for the kthreadnamecopy system call zvrfykthreadnamecopy in kernel/thread.c calls kobjectfind on the caller-supplied thread pointer and then dereferences the returned struct kobject without checking it for NULL. kobjectfind returns NULL whenever the suppli...

CVE-2026-10671

CVE-2026-10671 affects Zephyr kernel: the userspace verifier for k_pipe_init used K_SYSCALL_OBJ(), allowing an unprivileged thread with access to a k_pipe object to re-init a live pipe. This re-initialization clears the ring buffer and wait queues without accounting for current blockers, leaving ...

EUVD-2026-43244

Zephyr's dynamic kernel-object tracking kernel/userspace/userspace.c, formerly kernel/userspace.c maintains a doubly-linked list objlist of dynamically allocated kernel objects. Iteration over this list in kobjectwordlistforeach was performed under listslock using the SAFE iterator which caches t...
