AMD SEV-SNP: A Confidential Computing Primer

This paper is a technical primer on AMD Secure Encrypted Virtualization with Secure Nested Paging SEV-SNP, a hardware confidential computing implementation that provides Trusted Execution Environments TEEs for virtual machines. SEV-SNP treats the hypervisor as adversarial. It encrypts guest memor...

The vulnerability of the tee_shm_register_user_buf() function in the drivers/tee/tee_shm.c module of the Linux kernel’s trusted execution environment allows a attacker to cause a service failure.

The vulnerability of the teeshmregisteruserbuf function in the drivers/tee/teeshm.c module of the Linux kernel’s trusted execution environment is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

KS-CFA: Control-Flow Attestation Via Symbolic Replay against Control-Flow Bending Attacks

Control-flow attestation CFA enables a remote entity to verify program execution on a target device by monitoring control-flow behaviour at runtime. However, control-flow bending CFB attacks remain difficult to detect, where an adversary steers execution along legal edges of the program's...

CVE-2026-42546

A flaw was found in OP-TEE, a Trusted Execution Environment TEE for Arm Cortex-A cores. A resource leak exists in the shared memory cleanup logic where the system fails to properly release memory objects when processing non-contiguous memory parameters from a normal-world caller. Over time, these...

CVE-2026-40257

A flaw was found in OP-TEE Trusted Execution Environment. An off-by-one error in the ARM Crypto Extensions accelerated SHA-3 implementation can lead to a massive heap overflow. This vulnerability allows for the corruption of all TEE kernel memory, potentially impacting the integrity and...
