Trusted Model Environment for Private Semantic Computations

A private semantic computation primitive enables parties to privately compute over structured and unstructured data that requires understanding its semantics, context, and relationships. Standard cryptographic primitives e.g., multiparty computation do not readily support such computation...

CVE-2026-92701

Cocos AI is a confidential computing system for running AI workloads inside trusted execution environments. In versions up to and including 0.8.2, the intra-handshake attested TLS aTLS Intel TDX verification path does not copy the expected current-session freshness value into the TDX quote-body...

Towards TEE-Certified DP: Verifiable Differentially Private Training on Legacy GPUs

Wide adoption of machine learning has created growing policy and regulatory demand for protecting sensitive training data, with differential privacy DP emerging as a key mechanism. Yet a less-studied problem is how to certify the faithful execution of DP during training: an external verifier shou...

CVE-2026-56941

In multiple functions of fpcteehal.c, there is a possible use-after-free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

PT-2026-92319

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description A logic error in multiple functions within fpc tee hal.c allows for a use-after-free condition. This occurs when a program continues to use a pointer after it ha...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tee: optee: Fixed the kernel panic caused by incorrect error handling. The error path when failing to register devices on the TEE bus contains a bug that leads to kernel panic. The details are as follows: 15.398930 Unable to hand...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tee: Fix NULL pointer dereference in teeshmput teeshmput has a NULL pointer dereference: opteedisableshmcache shm = regpairtoptr...; // shm may return NULL teeshmfreeshm; teeshmputshm; // results in a crash Add a check in...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free exists in the drivers/tee/teeshm.c file within the TEE subsystem of the Linux kernel, as of version 5.15.11. This issue arises due to a race condition during the teeshmgetfromid function, when attempting to free a shared memory object...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: tee: amdtee: fixed an issue where ISERR returned NULL instead of an error pointer. The getfreepages function no longer returns error pointers; it now returns NULL. Therefore, this condition needs to be corrected to prevent NUL...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tee: added a overflow check in registershmhelper When special lengths are provided by the user space, registershmhelper may cause an integer overflow when calculating the number of pages covered by a given user space memory regio...

HermiCache: Enclave-Aware Cache Replacement for Trusted Execution Environments

Trusted Execution Environments TEEs protect enclave memory from untrusted software but remain vulnerable to cache-based side-channel attacks due to shared microarchitectural resources. Existing countermeasures use techniques such as cache partitioning or randomization: these solutions are not ide...

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

The vulnerability of the registershmhelper function in the drivers/tee/teeshm.c file of the Linux kernel’s trusted execution environment driver relates to the failure to release resources after their useful life has ended. Exploiting this vulnerability could allow an attacker to cause a service...

SUSE CVE-2026-80524

In the Linux kernel, the following vulnerability has been resolved: optee: ffa: Add NULL check in opteeffalendprotmem Sashiko locally reports a possible null dereference under memory pressure due to the lack of validation of the allocated pointer. Fix that by adding the missing check...

CVE-2026-80524

A flaw was found in the Linux kernel's OP-TEE Open Portable Trusted Execution Environment Fast Fault-tolerant Architecture FFA component. A local attacker could exploit a missing null check when allocating protected memory. Under specific memory pressure conditions, this could lead to a null...

PRISM: Lightweight Enclave Isolation with Prismatic Capabilities

Trusted execution environments TEEs protect sensitive code and data from external interference, but lack inherent memory safety. CHERI can enforce spatial memory safety at the object level. Attempts to establish a TEE using CHERI primitives suffer from 1 expensive capability revocation operations...

Benchmarking Confidential Computing Performance on NVIDIA Blackwell GPUs

This paper measures the performance impact of running large language model inference and training inside a Trusted Execution Environment TEE on NVIDIA B200 GPUs, using Intel Trust Domain Extensions TDX confidential VMs together with NVIDIA Confidential Computing CC on Blackwell GPUs. The...

Securing Filesystems for Confidential Computing

Confidential computing protects applications inside Trusted Execution Environments TEEs, but it leaves storage vulnerable. Even with disk encryption, a malicious cloud provider can roll back, replay, fork, or tamper with disk state, breaking the integrity and freshness guarantees required by...
