A patch is available and fixed versions include Linux kernel 7.0.0 and later releases listed in the advisory. Users should update to these fixed kernel versions to resolve the issue.
Description
A vulnerability in the Linux kernel's iio adc ti-ads1119 driver caused a power management (PM) reference leak during buffer preenable. If an I2C write operation fails, the runtime PM usage counter remains elevated, potentially leaving the device runtime-active indefinitely. This issue has been fixed in Linux kernel versions 7.0.0 and later.
