In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
power: supply: ucs1002: fix use-after-free on remove<\/p>\n
ucs1002 has no remove callback, so unbind runs entirely through devm.
\nThe alert IRQ handler queues the health_poll delayed work, and the work
\nreschedules itself while the chip reports a bad-health condition. devm
\nfrees the alert IRQ, which only synchronizes the handler; it does not
\ncancel the delayed work, which can then run after devm frees the driver
\ndata and dereference it.<\/p>\n
Register health_poll with devm_delayed_work_autocancel() before the
\nalert IRQ is requested. devm then frees the IRQ before cancelling the
\nwork, so the handler can no longer queue it and the work is cancelled
\nbefore the driver data is freed.<\/p>\n
