Introduction The GoTEE framework implements concurrent instantiation of TamaGo based unikernels in privileged and unprivileged modes, interacting with each other through monitor mode and custom system calls. With these capabilities GoTEE implements a TamaGo based Trusted Execution Environments TE...
CVE-2026-19575
The user-mode verification handler for the devicedeinit system call, zvrfydevicedeinit in kernel/device.c, validated its dev argument with KSYSCALLOBJINITdev, KOBJANY. kobjectvalidate short-circuits its type comparison when the requested type is KOBJANY, so the check reduced to "this pointer is t...

CVE-2026-19184: Out-of-bounds Write
The NXP GAU ADC driver drivers/adc/adcmcuxgauadc.c validated the caller-supplied sequence-buffersize, which is expressed in bytes, against the number of active channels, which is a sample count. It then stored that byte count directly in data-resultslength and used it in mcuxgauadcreadsamples as...
CVE-2026-17053
The Zephyr RTOS SMBus driver API contains a vulnerability where smbus_smbalert_remove_cb() and smbus_host_notify_remove_cb() are exposed as syscalls. These syscalls fail to perform K_SYSCALL_MEMORY_READ/WRITE validation on the caller-supplied struct smbus_callback *cb pointer, forwarding it direc...

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-2026-29646
In OpenXiangShan NEMU prior to 55295c4, when running with RVH Hypervisor extension enabled, a VS-mode guest write to the supervisor interrupt-enable CSR sie may be handled incorrectly and can influence machine-level interrupt enable state mie. This breaks privilege/virtualization isolation and ca...
CVE-2025-63384
A vulnerability was discovered in RISC-V Rocket-Chip v1.6 and before implementation where the SRET Supervisor-mode Exception Return instruction fails to correctly transition the processor's privilege level. Instead of downgrading from Machine-mode M-mode to Supervisor-mode S-mode as specified by...

CVE-2025-63384
The RISC-V Rocket-Chip (version 1.6 and earlier) contains a privilege retention vulnerability due to a flaw in the SRET (Supervisor-mode Exception Return) instruction handling. The processor fails to correctly transition from Machine-mode (M-mode) to Supervisor-mode (S-mode) as required by the ss...
