CVE-2023-32885
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 display drm, there is a possible memory corruption due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07780685; Issue ID: ALPS07780685.
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 missing bounds check in the Linux kernel's Direct Rendering Manager (DRM) display subsystem allows memory corruption, enabling local privilege escalation from System-level execution privileges. The vulnerability requires no user interaction and stems from insufficient input validation in the display driver code.

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 Android versionRun 'getprop ro.build.version.release' in a shell or check Settings > About Phone > Android versionAffected if The reported version is exactly 12.0 or 13.0
-
Verify System-level execution contextCheck if your process or application runs with System-level privileges (uid 1000) or if you have access to a shell with System-level rights using 'id' commandAffected if You have or can obtain System-level execution privileges on the device
-
Confirm DRM display driver presenceCheck if the device uses a DRM-based display driver by examining /sys/class/drm or running 'ls -la /dev/dri/'Affected if The device has a DRM display subsystem exposed at /dev/dri/ or /sys/class/drm
A device is affected if it runs Android 12.0 or 13.0 and the attacker can execute code at System privilege level to interact with the DRM display driver.

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.
dbcve · scopedApply the vendor patch ALPS07780685 or deploy the corresponding kernel security update to add proper bounds checking in the DRM display driver.
- 1. Check the Android Security Bulletin for the month when this vulnerability was patched. CVE-2023-32885 was addressed in the July 2023 Android Security Bulletin.
- 2. Contact your device manufacturer (OEM) to confirm they have integrated the MediaTek patch ALPS07780685 into their firmware.
- 3. Apply the OEM-provided system update that includes the July 2023 Android Security Patch Level or later.
- 4. Verify the patch has been applied by checking Settings > About Phone > Security Patch Level; it should show July 2023 or later.
