In the Linux kernel, the following vulnerability has been resolved:
spi: Fix null dereference on suspend
A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.
Example order of events leading to the exception:
Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.
