Linux Kernel TEe Optee Memory Error Reference Vulnerability

The Linux kernel is the core of the Linux operating system, responsible for managing hardware resources and providing system services. The TEE OP-TEE driver in the Linux kernel has a memory error reference vulnerability. This vulnerability arises from the possibility for the client to exit while...

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.
