CVE-2024-20081
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn gnss service, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08719602; Issue ID: MSV-1412.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA local privilege escalation vulnerability exists in the gnss service due to an out-of-bounds write caused by improper input validation. An attacker with System execution privileges can exploit this to elevate privileges further without user interaction.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if gnss service exists on the systemSearch for the gnss service binary or running process. On Linux-based systems, check common locations like /system/bin/gnss or look for processes named 'gnss' using 'ps -a | grep gnss' or similar process listing commands.Affected if The gnss service binary or process is present on the system
-
Verify the installed product versionDetermine the installed version of the operating system or platform (Yocto, RDK B, Android, or OpenWRT). On Android use 'getprop ro.build.version.release'; on Linux-based systems check /etc/version, /etc/os-release, or use 'uname -a'.Affected if The installed version matches exactly: Yocto 2.6, 3.3, or 4.0; RDK B 2022q3; Android 13.0 or 14.0; OpenWRT 19.07.0, 21.02.0, or 22.03.5
-
Confirm the gnss service is running with appropriate privilegesCheck the execution context and privilege level of the gnss service process. Determine if the service runs at System level privileges (one level below root) which is required for the attacker to exploit this privilege escalation.Affected if The gnss service runs with System-level execution privileges, which is the prerequisite privilege level an attacker needs to exploit this vulnerability
The environment is affected if it runs one of the specified product versions AND has the gnss service running with System-level privileges that the attacker can leverage for privilege escalation.
