CVE-2026-19676 PECI transfer syscall verifier does not validate embedded user buffer pointers, allowing arbitrary kernel memory read/write from user mode

The user-mode verifier for the pecitransfer system call, zvrfypecitransfer in drivers/peci/pecihandlers.c, checked only the device object permission and copied the caller-supplied struct pecimsg with kusermodefromcopy. That copy validates the outer structure only; the buf pointers and len values...

CVE-2026-19676

The peci_transfer() system call in the Zephyr RTOS (specifically within drivers/peci/peci_handlers.c ) fails to properly validate embedded buffer pointers and length values in the peci_msg structure. While the verifier checks outer structure permissions, it allows caller-controlled pointers in th...

CVE-2026-19185 Unvalidated user-supplied buffer pointers in the I3C do_ccc system call handler allow kernel memory read/write from user mode

The system-call verifier for i3cdoccc in drivers/i3c/i3chandlers.c validated the outer struct i3ccccpayload, the broadcast ccc.data buffer and the targets.payloads array, but did not validate the per-target data buffers those array elements point at. Each struct i3cccctargetpayload carries its ow...

CVE-2026-19185 Unvalidated user-supplied buffer pointers in the I3C do_ccc system call handler allow kernel memory read/write from user mode

CVE-2026-19185

In Zephyr RTOS builds with CONFIG_USERSPACE, a vulnerability exists in the i3c_do_ccc() system call handler within drivers/i3c/i3c_handlers.c. The system-call verifier fails to validate per-target data buffers, allowing an unprivileged user-mode thread with I3C controller access to provide arbitr...

CVE-2026-23763

VB-Audio Matrix and Matrix Coconut versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively, contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver vbmatrixvaio64win10.sys. The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCT...

CVE-2026-23763: Exposure of Resource to Wrong Sphere

VB-Audio Matrix and Matrix Coconut versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively, contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver vbmatrixvaio64win10.sys. The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCT...

CVE-2025-62525: Improper Input Validation

OpenWrt Project is a Linux operating system targeting embedded devices. Prior to version 24.10.4, local users could read and write arbitrary kernel memory using the ioctls of the ltq-ptm driver which is used to drive the datapath of the DSL line. This only effects the lantiq target supporting...

CVE-2015-3625: Undefined Security Weakness

The NVIDIA GPU driver for FreeBSD R352 before 352.09, 346 before 346.72, R349 before 349.16, R343 before 343.36, R340 before 340.76, R337 before 337.25, R334 before 334.21, R331 before 331.113, and R304 before 304.125 allows local users with certain permissions to read or write arbitrary kernel...
