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 · unedited
In keyinstall, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07388790; Issue ID: ALPS07388790.

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 confidence

In the keyinstall component, an out-of-bounds read vulnerability exists due to a missing bounds check. This allows a local attacker to read memory contents beyond the intended buffer boundaries, leading to information disclosure. No special privileges or user interaction are required for exploitation.

MitigationApply the vendor patch ALPS07388790 to implement the missing bounds check in the keyinstall component. Verify the fix through local privilege escalation testing and memory access validation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version
    Navigate to Settings > About Phone or run 'getprop ro.build.version.release' via adb shell to determine the installed Android OS version
    Affected if Version is 11 or 12 (exact match to 11.0 or 12.0)
  2. Check Android security patch level
    Navigate to Settings > About Phone > Security patch level or run 'getprop ro.build.version.security_patch' via adb shell
    Affected if Patch level is earlier than the vendor fix date for ALPS07388790; a user is potentially affected if the patch is not applied
  3. Verify keyinstall component presence
    Run 'dumpsys keyinstall' or check /system/lib64/libkeyinstall.so via adb shell to confirm the keyinstall component is present on the device
    Affected if Component exists and the device runs a vulnerable Android version (11.0 or 12.0) without the security update

A user is affected if the device runs Android 11.0 or 12.0 and lacks the security patch addressing CVE-2022-32602 in the keyinstall component.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor patch ALPS07388790 to implement the missing bounds check in the keyinstall component. Verify the fix through local privilege escalation testing and memory access validation.

Recommended fix Moderate confidence
  1. Contact MediaTek or your device manufacturer to obtain the security patch ALPS07388790
  2. Apply the MediaTek-supplied patch to the keyinstall component
  3. Verify the patch was applied by checking the Android security patch level in Settings > About Phone > Security Patch Level
  4. Ensure the device receives the latest Android security updates from your device OEM
