Description
This security bulletin contains information about 4 vulnerabilities.
1) Privilege escalation (CVE-ID: CVE‑2017‑6289)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
