CVE-2021-0615
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 flv extractor, there is a possible out of bounds read due to an integer overflow. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS05561369; Issue ID: ALPS05561369.
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 confidenceAn integer overflow in the FLV extractor allows an out-of-bounds read when processing specially crafted FLV files, leading to local information disclosure. No user interaction or elevated privileges are required for exploitation.

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 OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is exactly 10.0 or 11.0
-
Identify FLV extraction capabilityCheck if any application or system service uses FLV media parsing - look for FLV-related libraries (libflv.so) or check running processes that handle FLV contentAffected if FLV extractor component is present and processes FLV files
-
Verify if untrusted FLV files are processedReview installed applications and system services that handle media files - check logs or file associations for .flv file processingAffected if The device processes FLV files from any source
-
Confirm no vendor patch appliedCheck system security patch level in Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch'Affected if Security patch level is earlier than ALPS05561369 or not listed
Device is affected if running Android 10.0 or 11.0 and processes FLV files without the ALPS05561369 security patch applied.
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 vendor patch ALPS05561369. Until the patch is available, consider restricting processing of untrusted FLV files and monitoring for unusual media file handling behavior.
Android 10.0/11.0 with March 2021 Security Patch Level or later
- Check if your Android device has received the March 2021 or later Android Security Patch Level (SPL)
- Apply system updates through Settings > System > Software Update > Check for updates
- If using a MediaTek-based device, ensure the device manufacturer has applied the MediaTek patch ALPS05561369
- Verify the installed SPL matches or exceeds March 2021 in Settings > About phone > Android security patch level
