Answer in brief
CVE-2026-41434 records a Low severity (CVSS 3.3) vulnerability in OP-TEE has unbounded recursion in sanitize_client_object(). The current sources do not mark it as known exploited. The current feed maps OP-TEE/optee_os (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 3.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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. Starting in version 3.10.0 and prior to version 4.11.0, an unbounded recursion can crash the PKCS#11 TA. Version 4.11.0 contains a patch. No known workarounds are available.
