Overview
CVE-2026-89461 is a known-severity vulnerability. It was published on September 11, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
power: supply: max17040: synchronize work cancellation on suspend
max17040_work() requeues itself after every poll. cancel_delayed_work()
only cancels a pending instance and does not wait for a callback that is
already running.
If system suspend races with the polling callback, the callback can
continue accessing the fuel gauge and requeue itself after the suspend
callback returns.
Use cancel_delayed_work_sync() to ensure polling is quiesced before
suspend completes.
Remediation
