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 4.5.0 and prior to version 4.11.0, the RSA PKCS1 v1.5 decryption implementation in the Hisilicon HPRE crypto driver...

CVE-2026-41515

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 3.9.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the NXP CAAM crypto driver uses...

CVE-2026-41514

OP-TEE affects Cortex-A TrustZone, with RSA-OAEP decryption in the Hisilicon HPRE driver vulnerable from v4.5.0 up to v4.11.0 due to non-constant-time memcmp() in label hash verification and multiple distinct error paths. This creates a padding oracle allowing plaintext recovery on ~1,000–2,000 a...

SUSE CVE-2026-53273

In the Linux kernel, the following vulnerability has been resolved: tee: optee: prevent use-after-free when the client exits before the supplicant Commit 70b0d6b0a199 "tee: optee: Fix supplicant wait loop" made the client wait as killable so it can be interrupted during shutdown or after 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...

CVE-2026-53273

CVE-2026-53273 describes a use-after-free in the Linux kernel TEE/OP-TEE path. When a client exits before the supplicant finishes processing, freed request memory could be dereferenced, enabling a potential crash or code execution path. The root cause is a race around request lifetime between the...
