In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
pinctrl: mediatek: use devm_gpiochip_add_data() for GPIO chip<\/p>\n
The gpio_chip is allocated with device-managed memory but registered with
\nthe non-managed gpiochip_add_data(). This was harmless while the drivers
\nwere built-in, but once they can be built as modules and unbound\/rmmod’d,
\ndevm frees the gpio_chip’s memory while it is still registered, causing a
\nuse-after-free.<\/p>\n
Register it with devm_gpiochip_add_data() so it shares the same
\ndevice-managed lifecycle, which also lets the manual gpiochip_remove()
\nerror paths go away.<\/p>\n","protected":false},"excerpt":{"rendered":"
