CVE-2026-0051
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 multiple functions of ubsan_throwing_runtime.cpp, there is a possible way to cause a system crash due to improper input validation. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.
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 confidenceA vulnerability exists in multiple functions within the UBSan (Undefined Behavior Sanitizer) throwing runtime library (ubsan_throwing_runtime.cpp). Due to improper input validation, an attacker can trigger a system crash leading to remote denial of service. No authentication or user interaction is 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 The version is 14.0, 15.0, or 16.0 exactly
-
Identify apps using UBSanCheck APK files or installed binaries for linkage to libubsan.so using 'strings <binary> | grep -i ubsan' or examine ELF headers with readelf -lAffected if Any application binary links to the UBSan runtime library on an affected Android version
-
Inspect UBSan runtime libraryLocate libubsan.so in /system/lib64/ or /system/lib/ and check its build info via 'strings libubsan.so | grep -i version' or file metadataAffected if The libubsan runtime is present and corresponds to the vulnerable LLVM version used in Android 14-16
-
Check build configuration for UBSan flagsReview application build configuration files (Android.mk, CMakeLists.txt, build.gradle) for -fsanitize=undefined flagsAffected if Build configuration enables UBSan (-fsanitize=undefined) and targets affected Android versions
You are affected if running Android 14.0, 15.0, or 16.0 and have applications or binaries compiled with UBSan enabled that link to the vulnerable UBSan runtime library.
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.
From vendor dataApply vendor-supplied patches or updates to the affected compiler toolchain/UBsan runtime. If no patch is available, consider disabling UBSan in production environments or restricting access to systems processing untrusted input through the sanitizer.
