Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

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

spi: cadence-qspi: fix pointer reference in runtime PM hooks

dev_get_drvdata() gets used to acquire the pointer to cqspi and the SPI controller. Neither embed the other; this lead to memory corruption.

On a given platform (Mobileye EyeQ5) the memory corruption is hidden inside cqspi->f_pdata. Also, this uninitialised memory is used as a mutex (ctlr->bus_lock_mutex) by spi_controller_suspend().
