CVE-2024-23696
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 RGXCreateZSBufferKM of rgxta3d.c, there is a possible arbitrary code execution due to a use after free. This could lead to local escalation of privilege in the kernel 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 · high confidenceA use-after-free vulnerability in the RGXCreateZSBufferKM function within the kernel-mode graphics driver (rgxta3d.c) allows a local attacker to achieve arbitrary code execution at kernel privilege level. No user interaction or additional privileges are required for exploitation.

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 PowerVR graphics driver presenceCheck if the device uses PowerVR Rogue graphics by looking for driver modules in /system/lib/modules/ or /vendor/lib/modules/ for files containing 'rgx' or 'pvr' in the name, or check /proc/modules for loaded graphics driver modulesAffected if The PowerVR graphics driver module is loaded or present on the device
-
Check for the vulnerable driver componentLook for the specific driver file rgxta3d.c or related kernel module files (*.ko) in the system partition or vendor partition that contain 'rgx' or 'ta3d' in the filenameAffected if The rgxta3d driver component or related PowerVR kernel module exists on the system
-
Verify graphics driver is actively usedCheck /proc/[pid]/maps or dmesg logs for references to the PowerVR driver or RGX functions, or check if the graphics HAL is using PowerVR by examining /vendor/lib/hw/ or /system/lib/hw/ for pvrsrvkm or similar driver filesAffected if The PowerVR kernel graphics driver is actively in use or the device uses PowerVR as its graphics backend
If the device has the PowerVR graphics driver (rgxta3d component) present and loaded, the vulnerability is applicable since all Android versions with this driver are affected.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-provided patch for this kernel driver vulnerability; until a patch is available, consider restricting access to the affected graphics driver module or disabling the associated subsystem if feasible.
