In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
power: supply: lp8788-charger: fix use-after-free on remove<\/p>\n
lp8788_charger_remove() flushes charger_work before unregistering the
\nIRQs. An IRQ thread can queue charger_work after flush_work() has
\nreturned. The work can then run after devres frees pchg and dereference
\nit in lp8788_charger_event().<\/p>\n
Unregister the IRQs first. free_irq() waits for any running threaded
\nhandler, so no handler can queue more work afterwards. Then use
\ncancel_work_sync() to cancel pending work or wait for running work to
\nfinish.<\/p>\n
