CVE-2024-32903
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 prepare_response_locked of lwis_transaction.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege 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 · high confidenceA kernel-level out-of-bounds write vulnerability exists in the prepare_response_locked function of lwis_transaction.c due to improper input validation. This allows a local attacker to corrupt memory and escalate privileges to root without requiring user interaction or additional execution privileges.

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.
-
Confirm device runs AndroidCheck /system/build.prop or run 'getprop ro.build.version.release' to verify the operating system is Google AndroidAffected if The device runs any version of Android (all versions are affected)
-
Identify kernel versionRun 'uname -r' or check /proc/version to determine the kernel versionAffected if The kernel version has not been patched to include the fix for CVE-2024-32903 in lwis_transaction.c
-
Check if lwis driver is presentSearch for lwis.ko module in /lib/modules/ or check kernel config via /proc/config.gz for CONFIG_LWIS, or grep for 'lwis' in /proc/kallsymsAffected if The lwis driver is compiled into the kernel or loaded as a module (vulnerability only applies if driver is present)
-
Verify driver source has patchIf you have access to the driver binary or source, inspect prepare_response_locked function in lwis_transaction.c for proper input validation bounds checkingAffected if The prepare_response_locked function lacks proper input validation allowing out-of-bounds write
A user is affected if the device runs Android with an unpatched kernel containing the lwis driver where prepare_response_locked lacks input validation.

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 the vendor-provided security patch for lwis_transaction.c to implement proper input validation in prepare_response_locked, then rebuild and deploy the updated kernel/driver.
