CVE-2024-26807
medium
Description
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().
