Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Linux kernel MediaTek pinctrl driver versions from 4.1 are affected. The GPIO chip is registered with a non-managed call although its memory is device-managed, so unbinding or removing the driver built as a module can cause a use-after-free. Upgrade to 6.1.191, 6.6.160, 6.12.114, 6.18.57 or later in the matching stable series.
