CVE-2026-93070

In the Linux kernel, the following vulnerability has been resolved:

media: ipu6: Do not free aux device pdata after init

ipu6_bus_initialize_device() stores the isys/psys pdata pointer in
struct ipu6_bus_device and initializes the auxiliary device. After that
point, error unwinding must drop the auxiliary device reference and let
ipu6_bus_release() free both the bus device and adev->pdata.

The isys and psys init paths already call put_device() when MMU
initialization fails, and ipu6_bus_add_device() calls
auxiliary_device_uninit() on auxiliary_device_add() failure. Both paths
therefore run the bus release callback. The extra kfree(pdata) in the
callers can release the same object a second time.

Remove the manual pdata frees after the auxiliary device has been
initialized.

This issue was found by a static analysis checker and confirmed by
manual source review.
