CVE-2026-98657
NONEDescription
In the Linux kernel, the following vulnerability has been resolved:
iio: proximity: pulsedlight: fix iio_device left registered on PM setup failure
pm_runtime_set_active() failing in probe() jumps to error_unreg_buffer,
which only calls iio_triggered_buffer_cleanup() -- it does not undo the
iio_device_register() that already succeeded a few lines above. probe()
then returns the error, the devm-managed indio_dev is freed, but the
iio core still has it registered: the sysfs/chardev nodes stay live and
point at freed memory.
Add an error_unreg_dev label that unregisters the iio device before
falling through to the existing buffer cleanup, mirroring the teardown
order already used in lidar_remove().
