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 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: ALPS07537393; Issue ID: ALPS07180396.

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

An out-of-bounds write vulnerability exists in the ISP (Image Signal Processor) component due to a missing bounds check. An attacker with system-level privileges could exploit this memory corruption issue to escalate privileges to root.

MitigationApply vendor patch ALPS07537393 which adds the missing bounds check in the ISP component. This is a targeted patch that should be tested thoroughly on the specific device model.

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. Verify Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is 12.0 or 13.0 exactly (not a later security patch update)
  2. Confirm ISP hardware presence
    Check device specifications for ISP (Image Signal Processor) in the SoC, or inspect kernel modules for isp-related drivers via 'ls /vendor/lib/modules/' or check /proc/device-tree/ for ISP nodes
    Affected if Device has an ISP component (present in most Android smartphones with cameras)
  3. Check security patch level
    Go to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB
    Affected if The security patch level is earlier than the date when ALPS07537393 was released (patch not yet applied)
  4. Verify vendor-specific ISP patch status
    Consult device manufacturer documentation or security bulletin for patch ALPS07537393 status, or check vendor-specific build properties via 'getprop' | grep -i isp
    Affected if Vendor patch ALPS07537393 has not been applied to the ISP component

Device is affected if running Android 12.0 or 13.0 and the ISP component has not received vendor patch ALPS07537393 (check via security patch level or vendor documentation).

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

Apply vendor patch ALPS07537393 which adds the missing bounds check in the ISP component. This is a targeted patch that should be tested thoroughly on the specific device model.

Recommended fix Moderate confidence

Android 12.0/13.0 with the security patch level containing ALPS07537393 (typically included in Android Security Bulletins from early 2023)

  1. 1. Check the Android Security Bulletin for the month the patch ALPS07537393 was released (refer to source: corp.mediatek.com)
  2. 2. Apply the corresponding Android system security update that includes the MediaTek ISP fix
  3. 3. Verify the device has the latest security patch level installed via Settings > About Phone > Security Patch Level
  4. 4. If the device manufacturer has released a specific firmware update incorporating MediaTek patch ALPS07537393, apply that update
Caveat Security updates are low-risk; ensure backup of data before applying major system updates
