Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Security restrictions bypass (CVE-ID: CVE-2021-1106)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in nvmap in NVIDIA Linux kernel distributions due to possibility to perform writes to read-only buffers. A local user can execute arbitrary code with kernel privileges.


2) Improper access control (CVE-ID: CVE-2021-1107)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper access control restrictions in nvmap NVMAP_IOC_WRITE* paths. A local user can execute arbitrary code with kernel privileges.


3) Integer overflow (CVE-ID: CVE-2021-1108)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow in FuSa Capture (VI/ISP). A local user can run a specially crafted program to execute arbitrary code with elevated privileges.

4) Resource management error (CVE-ID: CVE-2021-1109)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources. A multistep, timing-related vulnerability where an unauthorized modification by camera resources may result in denial of service.


5) Input validation error (CVE-ID: CVE-2021-1110)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in camera firmware. A local user can pass specially crafted input to the application and perform a denial of service (DoS) attack.


6) Buffer overflow (CVE-ID: CVE-2021-1111)

The vulnerability allows an attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Bootloader. An attacker with physical access through USB to the system can trigger memory corruption and execute arbitrary code.


7) NULL pointer dereference (CVE-ID: CVE-2021-1112)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in nvmap. A local userr can pass specially crafted data to the system and perform a denial of service (DoS) attack.


8) Security restrictions bypass (CVE-ID: CVE-2021-1113)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to unauthorized modification by camera resources. A local user can perform a denial of service attack.


9) Use-after-free (CVE-ID: CVE-2021-1114)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error in the kernel crypto node. A local user can trigger a use-after-free error and perform a denial of service (DoS) attack.
