Overview

CVE-2024-35883 is a medium-severity vulnerability. It was published on May 19, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
