Summary
In the Linux kernel, the following vulnerability has been resolved: spi: fsi: Implement a timeout for polling status The data transfer routines must poll the status register to determine when more data can be shifted in or out. If the hardware gets into a bad state, these polling loops may never exit. Prevent this by returning an error if a timeout is exceeded.
