CVE-2023-32864
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 out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07292187; Issue ID: ALPS07292187.
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 vulnerability in the Linux kernel's Direct Rendering Manager (DRM) subsystem allows an out-of-bounds write due to an incorrect bounds check. This memory corruption issue can be exploited for local privilege escalation, though the attacker already needs System-level execution privileges.

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 Android versionRun 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if Version is 12.0 or 13.0 exactly
-
Confirm kernel versionRun 'uname -a' to check the running kernel versionAffected if Kernel version corresponds to the affected Android releases (12.0 or 13.0)
-
Identify loaded DRM driversCheck /proc/drivers or use 'lsmod' to list loaded kernel modules related to DRM (such as GPU/display drivers)Affected if Any DRM driver module is loaded and active
-
Verify DRM subsystem is activeCheck /sys/class/drm/ for DRM device nodes or run 'dmesg | grep drm' to see DRM initialization messagesAffected if DRM subsystem is initialized and in use on the device
A device is affected if it runs Android 12.0 or 13.0 and has an active DRM subsystem with the vulnerable driver present, since the bounds check flaw in the DRM driver can then be triggered for memory corruption.
Generated from the published advisory. Verify against your own configuration.
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 (ALPS07292187) to correct the bounds check logic in the affected DRM driver to prevent memory corruption.
Android Security Patch Level July 2023 or later (containing MediaTek ALPS07292187 fix)
- 1. Verify the device uses a MediaTek SoC by checking the device specifications or using a system info app
- 2. Check the current Android Security Patch Level by going to Settings > About Phone > Software Information > Security Patch Level
- 3. Apply the July 2023 Android Security Update or later, which contains the fix for this vulnerability (Patch ID ALPS07292187)
- 4. This can be done via: Settings > System > Software Update > Download and Install (if available from device OEM)
- 5. Alternatively, contact the device manufacturer (OEM) for the specific firmware update containing the MediaTek fix
- 6. Verify the update was applied successfully by checking the Security Patch Level shows July 2023 or later
