Overview

CVE-2024-47751 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

PCI: kirin: Fix buffer overflow in kirin_pcie_parse_port()

Within kirin_pcie_parse_port(), the pcie->num_slots is compared to

pcie->gpio_id_reset size (MAX_PCI_SLOTS) which is correct and would lead

to an overflow.

Thus, fix condition to pcie->num_slots + 1 >= MAX_PCI_SLOTS and move

pcie->num_slots increment below the if-statement to avoid out-of-bounds

array access.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
