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: ALPS07310780; Issue ID: ALPS07310780.

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 in the ISP (Image Signal Processor) component due to missing bounds checking, allowing local privilege escalation from System execution privileges. The vulnerability does not require user interaction.

MitigationApply vendor patch ALPS07310780 which adds proper bounds validation to prevent the out-of-bounds write condition in the ISP driver.

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 is 12.0
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via adb shell
    Affected if Android version shows exactly 12.0 (not 11.0, 12L, 13, or later)
  2. Check vendor patch level
    Go to Settings > About Phone > Build number, or run 'getprop ro.build.version.security_patch' via adb shell
    Affected if The patch level is earlier than the date when ALPS07310780 was applied, or the specific patch is not listed in system updates
  3. Identify ISP driver presence
    Run 'ls /vendor/lib/modules/' or check for isp-related kernel modules via 'lsmod | grep -i isp' in adb shell with root access
    Affected if ISP driver modules exist in /vendor/lib/modules/ and the device uses a MediaTek chipset (common for ALPS-referenced vulnerabilities)
  4. Check MediaTek secure patch level
    Run 'getprop ro.build.version.alps' or 'getprop ro.vendor.mtk的安全补丁级别' via adb shell to check vendor-specific patch status
    Affected if The ALPS patch level is not listed or shows a version prior to the fix containing ALPS07310780

Affected if running Android 12.0 on a MediaTek-based device without the ALPS07310780 vendor patch applied to the ISP driver.
