CVE-2024-35883

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe<br /> <br /> In function pci1xxxx_spi_probe, there is a potential null pointer that<br /> may be caused by a failed memory allocation by the function devm_kzalloc.<br /> Hence, a null pointer check needs to be added to prevent null pointer<br /> dereferencing later in the code.<br /> <br /> To fix this issue, spi_bus-&gt;spi_int[iter] should be checked. The memory<br /> allocated by devm_kzalloc will be automatically released, so just directly<br /> return -ENOMEM without worrying about memory leaks.
