CVE-2026-53210

A flaw was found in the Linux kernel's Trusted Execution Environment TEE subsystem. A shared memory shm leak occurs in the registershmhelper function when TEEIOCSHMREGISTER is called with a zero-length shared memory registration. This can be triggered by a local attacker, potentially leading to a...

CVE-2026-53273

A flaw was found in the Linux kernel's Trusted Execution Environment TEE subsystem, specifically within the OP-TEE driver. This use-after-free vulnerability occurs when a client task terminates before its associated supplicant has finished processing a request. This timing issue can lead to the...

UBUNTU-CVE-2026-53210

In the Linux kernel, the following vulnerability has been resolved: tee: shm: fix shm leak in registershmhelper registershmhelper allocates shm before calling ioviternpages. If ioviternpages returns 0, the function jumps to errctxput and leaks shm. This can be triggered by TEEIOCSHMREGISTER with...

CVE-2026-45328

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.5.4 and 6.0, the esptee component exposes secure-service wrappers in espsecureservices.c and espsecureservicesiram.c that bridge calls from the user application i.e. the REE to TEE-protected hardware peripherals...

EUVD-2026-35917

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.5.4 and 6.0, several ESP-TEE secure-service wrappers in espsecureservices.c and espsecureservicesiram.c validated only some of the caller-supplied pointer arguments, leaving input pointer arguments unchecked...

CVE-2026-45328

The CVE concerns ESF-IDF’s ESP-IDF esp_tee component. In versions 5.5.4 and 6.0, the secure-service wrappers in esp_secure_services.c and esp_secure_services_iram.c bridge calls from the REE to TEE-protected peripherals (AES, SHA, ECC, HMAC, SPI, MMU, WDT) and security features (attestation, OTA,...

Name of the Vulnerable Software and Affected Versions ESF-IDF versions 5.5.4 ESF-IDF version 6.0 Description Several ESP-TEE secure-service wrappers in esp secure services.c and esp secure services iram.c fail to validate all caller-supplied pointer arguments. Since the TEE-protected hardware...

Space Fabric: A Satellite-Enhanced Trusted Execution Architecture

The emergence of decentralized satellite networks and orbital computing platforms creates a pressing need for trust architectures that can operate without physical access to the hardware, without reliance on pre-provisioned vendor secrets, and without dependence on a single manufacturer's...

CVE-2026-40290

A flaw was found in OP-TEE Trusted Execution Environment. A local attacker could exploit a user-after-free UAF race condition in the shared memory teardown logic when OP-TEE is configured as a Secure Partition Management Controller SPMC for Secure EL0 S-EL0 Secure Partitions. This vulnerability...

CVE-2026-0428

Insufficient parameter sanitization in TEE SOC Driver could allow an attacker to issue a malformed DRVSOCCMDIDSRIOVCOPYVFCHIPLETREGS to write invalid data to a remote Die, potentially resulting in unexpected behavior...

CVE-2026-33662

OP-TEE is a Trusted Execution Environment TEE designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. From 3.8.0 to 4.10, in the function emsapkcs1v15encode in core/drivers/crypto/cryptoapi/acipher/rsassa.c, the amount of padding needed, "...

Opportunities and Challenges in Securely Reusing and Repurposing Mobile Devices

An estimated 5.3 billion mobile phones became electronic waste in 2022. Many of these devices can be repurposed and used in different contexts to extend their lifetime and to reduce ecological impacts. An often overlooked aspect of smartphone reuse is cybersecurity: these devices embed...

CVE-2026-45614

A flaw was found in OP-TEE Trusted Execution Environment. This vulnerability allows a local attacker to reconstruct the private key by providing approximately 30-40 specially crafted public keys during the Elliptic Curve Diffie-Hellman ECDH shared secret generation. The system fails to verify if...
