📛 CVE Title

power: supply: goldfish: Fix use-after-free in power_supply_changed()

Description

In the Linux kernel, the following vulnerability has been resolved: power: supply: goldfish: Fix use-after-free in power_supply_changed() Using the `devm_` variant for requesting IRQ _before_ the `devm_` variant for allocating/registering the `power_supply` handle, means that the `power_supply` handle will be deallocated/unregistered _before_ the interrupt handler (since `devm_` naturally deallocates in reverse allocation order). This means that during removal, there is a race condition where an interrupt can fire just _after_ the `power_supply` handle has been freed, *but* just _before_ the corresponding unregistration of the IRQ handler has run. This will lead to the IRQ handler calling `power_supply_changed()` with a freed `power_supply` handle. Which usually crashes the system or otherwise silently corrupts the memory... Note that there is a similar situation which can also happen during `probe()`; the possibility of an interrupt firing _before_ registering the `power_supply` handle. This would then lead to the nasty situation of using the `power_supply` handle *uninitialized* in `power_supply_changed()`. Fix this racy use-after-free by making sure the IRQ is requested _after_ the registration of the `power_supply` handle.

This means that during removal, there is a race\ncondition where an interrupt can fire just _after_ the `power_supply`\nhandle has been freed, *but* just _before_ the corresponding\nunregistration of the IRQ handler has run.\n\nThis will lead to the IRQ handler calling `power_supply_changed()` with\na freed `power_supply` handle. Which usually crashes the system or\notherwise silently corrupts the memory...\n\nNote that there is a similar situation which can also happen during\n`probe()`; the possibility of an interrupt firing _before_ registering\nthe `power_supply` handle. This would then lead to the nasty situation\nof using the `power_supply` handle *uninitialized* in\n`power_supply_changed()`.\n\nFix this racy use-after-free by making sure the IRQ is requested _after_\nthe registration of the `power_supply` handle."
