Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A use-after-free issue exists in the ti-qspi SPI driver. The driver is designed to fall back to PIO (Programmed Input/Output) mode if DMA (Direct Memory Access) setup fails during the probe process. However, if buffer allocation fails, the DMA channel pointer is not cleared. This can lead to the system passing a pointer to a released channel to the DMA engine or attempting to free the channel a second time during driver unbind or late probe errors.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
