CVE-2024-24862 Information

Description

In function pci1xxxx_spi_probe there is a potential null pointer that may be caused by a failed memory allocation by the function devm_kzalloc. Hence a null pointer check needs to be added to prevent null pointer dereferencing later in the code.

To fix this issue spi_bus->spi_int[iter] should be checked. The memory allocated by devm_kzalloc will be automatically released so just directly return -ENOMEM without worrying about memory leaks.
