# Lenovo Tablets: third-party app can write files with elevated privileges

Link for people: https://infrastack.ai/live/CVE-2026-116633 (this .md is for agents)

Some Lenovo tablets have a flaw that lets a third-party application write arbitrary files with elevated privileges. An attacker who gets a malicious app onto the device could change protected system files.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Lenovo Tablets affected range not listed fixed no fixed version listed

## How to check

On the tablet open Settings > About tablet and note the model number (e.g. TB373FU) and build/firmware version. Compare with the Lenovo product security advisory for this CVE (probably https://support.lenovo.com/us/en/product_security/ps500890, not readable by me; unconfirmed). A CVE-record mirror lists firmware up to 17.5.10.107 for TB373FU, 17.0.10.324 for TB305FU, 17.5.10.348 for TB336FU, but these ranges are unverified and do not say which build is fixed.
