CVE-2022-21792
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 camera isp, there is a possible out of bounds write 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: ALPS07085410; Issue ID: ALPS07085410.
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 missing bounds check in the camera ISP (Image Signal Processor) allows an out-of-bounds write, leading to memory corruption. This enables local privilege escalation from an app with System execution privileges, 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.
-
Check Android versionGo to Settings > About Phone > Android version and verify if the installed version is exactly 11.0 or 12.0Affected if Android version is 11.0 or 12.0 exactly (not a later patched version)
-
Check vendor security patch levelGo to Settings > About Phone > Security patch level and note the date. Compare against the date when ALPS07085410 patch was released for your device modelAffected if Security patch level predates the ALPS07085410 patch release date for your specific device model
-
Verify camera ISP hardware presenceCheck device specifications or use a system info app to confirm the device has a camera ISP (Image Signal Processor) componentAffected if Device has a camera ISP and is running affected Android versions 11.0 or 12.0
A user is affected if their device runs Android 11.0 or 12.0 and has not received the vendor-specific ALPS07085410 firmware patch for the camera ISP subsystem.
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 patch ALPS07085410 through the device/vendor firmware update channel and verify camera functionality post-update.
Apply the latest Android security update from your device OEM that includes MediaTek patch ALPS07085410 (typically the March 2022 or later Android Security Patch Level)
- 1. Check if your Android device uses a MediaTek chipset by reviewing the device specifications or using a system information app
- 2. Contact your device manufacturer (OEM) to confirm they have released a security update containing MediaTek patch ALPS07085410
- 3. Apply the latest Android security patch update from your device manufacturer - this should include the MediaTek camera ISP fix
- 4. Verify the update was applied by checking Settings > About Phone > Security Patch Level
