Linux Distros Unpatched Vulnerability : CVE-2026-89465

medium Nessus Plugin ID 345259

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- power: supply: rt9455: quiesce delayed work before teardown The threaded IRQ handler can queue pwr_rdy_work, max_charging_time_work and batt_presence_work. pwr_rdy_work and batt_presence_work can also queue max_charging_time_work, while batt_presence_work can requeue itself. rt9455_remove() cancels max_charging_time_work before batt_presence_work. The latter can therefore queue max_charging_time_work after it has already been cancelled: rt9455_remove() workqueue cancel pwr_rdy_work cancel max_charging_time_work batt_presence_work queues max_charging_time_work cancel batt_presence_work return devres frees rt9455_info max_charging_time_work dereferences rt9455_info The IRQ also remains registered until devres cleanup and can queue more work after any of the cancellation calls. If rt9455_hw_init() fails after the IRQ has been requested, probe returns without cancelling work that may already have been queued. A pending callback can then access rt9455_info after it has been freed. Register rt9455_cancel_all_delayed_works() through devm_add_action_or_reset() right after devm_power_supply_register(). devres invokes the action in reverse registration order, after the managed IRQ has been freed and before rt9455_info is released, so the delayed works are drained in both rt9455_remove() and the probe error path. Cancel pwr_rdy_work and batt_presence_work before max_charging_time_work because both can queue the latter. This issue was found by an in-house static analysis tool. (CVE-2026-89465)

Note that Nessus relies on the presence of the package as reported by the vendor.
