Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: power: supply: bq256xx: drain usb_work before freeing the charger The USB-PHY notifier queues usb_work, whose handler calls power_supply_changed(bq->charger). The reset devm action only unregisters the notifier and was registered before the power supplies, so devm frees bq->charger on unwind before the action runs; a usb_work still queued can then dereference it. Register the reset action after the power supplies, so it unregisters the notifiers and drains usb_work before the supplies are released. Initialize usb_work and obtain the PHY references before registering the notifiers, so the worker cannot run before the supplies exist. Found by static analysis.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
