CVE-2026-14961: Improper Input Validation

Pegatron Tdelo64.sys exposes a privileged device interface, \.\TdeIo, that fails to properly restrict access to sensitive IOCTL functionality. The driver's IOCTL dispatcher does not validate caller privileges or verify user-supplied kernel memory addresses before performing memory operations. By...

Privilege escalation vulnerability via unprotected IOCTL interface in Pegatron Tdelo64.sys

Overview A privilege escalation vulnerability exists in the tdeio64.sys driver due to an unprotected input/output control IOCTL dispatch routine that fails to validate the origin and permissions of user-supplied requests. An unprivileged local attacker can abuse exposed IOCTL dispatch routines...

CVE-2026-10669

On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...

CVE-2026-10669

Summary (CVE-2026-10669) : On Xtensa SoCs with CONFIG_XTENSA_MPU and CONFIG_USERSPACE, arch_buffer_validate() erroneously permits access when the buffer size rounds to a wrap of the 32-bit address space, bypassing MPU checks. This can let an unprivileged user-thread validate or copy memory it sho...

CVE-2026-10667

Zephyr CVE-2026-10667 affects SMP builds with CONFIG_USERSPACE and dynamic objects (CONFIG_DYNAMIC_OBJECTS). The bug is a use-after-free in the dynamic kernel-object tracker: k_object_wordlist_foreach() iterates obj_list under lists_lock while removals and frees occur under objfree_lock/obj_lock,...

CVE-2026-10667 SMP use-after-free in Zephyr `CONFIG_USERSPACE` dynamic kernel-object tracking, reachable from unprivileged user threads

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...

CVE-2026-41154

The GPU DDK is vulnerable to an out-of-bounds (OOB) memory access issue. The root cause is incorrect buffer indexing within the page freeing logic of the sparse memory implementation specifically when indexing pages larger than 4kB . An attacker running software as a non-privileged user may lever...

CVE-2026-41154
