CVE-2022-26451
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 ged, there is a possible use after free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07202966; Issue ID: ALPS07202966.
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 use-after-free vulnerability exists in ged (graphics execution driver) due to improper locking. This memory corruption flaw can be exploited locally to escalate privileges to System level without requiring 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.
-
Confirm Android version is 12.0Run 'getprop ro.build.version.release' or check /system/build.prop for ro.build.version.release=12.0Affected if Version is exactly 12.0 and no后续 security updates have been applied
-
Identify ged driver presenceCheck for ged driver in /proc or /sys filesystems, or use 'getprop' to query mediatek vendor properties related to ged (e.g., 'getprop | grep ged')Affected if ged driver is loaded and running on the device
-
Check ged patch levelQuery MediaTek-specific system properties for the ALPS patch status using 'getprop | grep alps' or check /vendor/etc/vendor.xml for patch ALPS07202966Affected if The patch ALPS07202966 is not listed in the applied patches or the ged component shows unpatched status
-
Verify exploitability conditionsExamine if the device allows local privilege escalation by checking if any untrusted app can access ged driver interfaces; review SELinux policies for ged driver access controlsAffected if The ged driver is accessible without proper restrictions and improper locking (race condition) still exists in the driver code
A device is affected if it runs Android 12.0 and the ged driver does not have patch ALPS07202966 applied, leaving the use-after-free vulnerability from improper locking exploitable for local privilege escalation to System level.

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 patch ALPS07202966 through firmware/ROM update from the device vendor. In custom builds, fix the locking mechanism in the ged component to prevent the race condition leading to use-after-free.
- Contact your device manufacturer (OEM) to request the security patch containing MediaTek patch ID ALPS07202966
- Verify with the manufacturer that the patch addresses CVE-2022-26451 specifically
- Apply the vendor-supplied patch through the normal OEM software update mechanism
- After patching, verify the ged component version includes the fix for ALPS07202966
