Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Privilege escalation (CVE-ID: CVE‑2017‑6289)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a flaw in the Tegra kernel driver. A local attacker can run a specially crafted application to execute arbitrary code within the Trusted Execution Experience (TEE) with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

2) Privilege escalation (CVE-ID: CVE‑2017‑6293)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a flaw in the Tegra kernel driver. A local attacker can run a specially crafted application to execute arbitrary code within the Tegra X1 TrustZone (TZ) with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

3) Privilege escalation (CVE-ID: CVE‑2017‑5715)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a flaw in the Tegra kernel driver. A local attacker can run a specially crafted application to execute arbitrary code within the Trusted Little Kernel (TLK) and gain access to arbitrary data.

4) Out-of-bounds read (CVE-ID: CVE‑2018‑6246)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to a boundary error in the Tegra kernel driver. A remote attacker can trigger out-of-bounds read in the TrustZone (TZ) with system execution privileges and gain access to arbitrary data.
