In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
platform\/x86: x86-android-tablets: hold device reference for secondary fwnode teardown<\/p>\n
In gpio_secondary_fwnode_init(), acpi_bus_find_device_by_name() returns a
\ndevice reference, but the local dev variable is declared with
\n__free(put_device), dropping the reference at the end of each iteration.
\nMeanwhile, devm_add_action_or_reset() saves the dev pointer for
\ngpio_secondary_unset() without incrementing its reference count, which
\ncould lead to a use-after-free during driver teardown if the device is
\nreleased in the interim.<\/p>\n
Acquire an explicit device reference with get_device() when registering
\nthe devres action, and drop it with put_device() inside
\ngpio_secondary_unset().<\/p>\n","protected":false},"excerpt":{"rendered":"
