Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.6.20/6.7.8. This vulnerability affects the function dev_get_drvdata of the component cadence-qspi. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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().

The advisory is available at git.kernel.org. This vulnerability was named CVE-2024-26807 since 02/19/2024. The exploitation appears to be easy. Technical details are known, but there is no available exploit.
