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 hevc decoder, 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: ALPS07491374; Issue ID: ALPS07491374.

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 confidence

A missing bounds check in the HEVC (H.265) video decoder allows an out-of-bounds write vulnerability, enabling local privilege escalation to System level without user interaction. The flaw exists in the decoder's processing of video bitstream data where array or buffer indices are not properly validated before write operations.

MitigationApply vendor patch ALPS07491374 which adds proper bounds checking in the HEVC decoder. Prioritize patching given the no-user-interaction requirement and System-level privilege escalation potential.

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 on the device
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if The displayed version is 10.0 or 11.0
  2. Confirm the build matches exact affected versions
    Review the full version string in Settings > About Phone > Build number, or run 'getprop ro.build.version.incremental' via ADB
    Affected if The build corresponds to Android 10.0 or Android 11.0 specifically (not 12.0 or higher)

If the device runs Android version 10.0 or 11.0, the HEVC decoder is vulnerable and the system is affected by this CVE.

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.
