CVE-2026-0143
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 lwis_device_external_event_emit of lwis_event.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with System 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 use-after-free vulnerability exists in the lwis_device_external_event_emit function in lwis_event.c. The function improperly handles memory objects, leading to memory corruption where freed memory is accessed after deallocation. This can be exploited for local privilege escalation from System 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 is running AndroidCheck /proc/version or run 'uname -a' and look for 'Android' in the outputAffected if Device is not running Android (this CVE only affects Android)
-
Check if lwis kernel module is loadedRun 'ls /sys/module | grep lwis' or check 'cat /proc/modules' for lwis entriesAffected if The lwis module is present and loaded in the kernel
-
Verify kernel version against patched releasesRun 'cat /proc/version' or 'uname -r' to get the exact kernel version, then compare against any Google Android security bulletins for CVE-2026-0143Affected if Kernel version is older than the patched version announced for this CVE
-
Check for vulnerable function in kernelExamine /sys/module/lwis/parameters if the module has parameters, or check the kernel config at /proc/config.gz if available for lwis supportAffected if The lwis driver is compiled into or loaded as a module on the device
A device is affected if it runs Android with the lwis driver present and has a kernel version prior to the patched release for CVE-2026-0143
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 the vendor-provided kernel patch for CVE-2026-0143 and update to a patched kernel version. If a patch is unavailable, consider disabling or isolating the affected lwis driver until a fix is available.
