Description
In the Linux kernel, the following vulnerability has been resolved:
spi: tegra20-slink: fix UAF in tegra_slink_remove()
After calling spi_unregister_master(), the refcount of master will be decrease to 0, and it will be freed in spi_controller_release(), the device data also will be freed, so it will lead a UAF when using 'tspi'. To fix this, get the master before unregister and put it when finish using it.
