CVE-2025-36905
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 gxp_mapping_create of gxp_mapping.c, there is a possible privilege escalation due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 logic error in the gxp_mapping_create function in gxp_mapping.c allows a local attacker to escalate privileges without requiring additional execution privileges or user interaction. The vulnerability stems from incorrect privilege checking logic in the mapping creation process.

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.
-
Identify the gxp_mapping.c componentSearch the Android system for files containing 'gxp_mapping' or 'gxp_mapping_create' - this may be in kernel drivers, TEE components, or vendor-specific code. Use 'find / -name '*gxp*' 2>/dev/null' or check vendor kernel source repositories.Affected if The gxp_mapping.c source file or compiled gxp_mapping module exists on the device
-
Determine if privilege mapping is accessibleExamine the gxp_mapping_create function logic - the vulnerability stems from incorrect privilege checking during mapping creation. Check if the code performs proper permission validation before allowing mapping creation.Affected if The mapping creation function has flawed privilege checking logic that allows unprivileged mapping creation
-
Check for local privilege escalation pathsReview how gxp_mapping_create handles resource allocation and privilege assignment. The logic error allows a local attacker to escalate privileges through mapping operations.Affected if The function permits privilege escalation without proper authorization checks
-
Verify Android version impactSince all Android versions are affected, confirm the Android version and kernel version in use. Check /system/build.prop or 'getprop ro.build.version.release' for Android version and 'uname -a' for kernel version.Affected if The device runs any version of Android, as all versions contain the vulnerable logic error
A user is affected if their Android device contains the gxp_mapping component with the flawed privilege checking logic in gxp_mapping_create that allows local privilege escalation.
