Overview

CVE-2024-35915 is a high-severity vulnerability. It was published on May 19, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

Technical description

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

nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet

syzbot reported the following uninit-value access issue [1][2]:

nci_rx_work() parses and processes received packet. When the payload

length is zero, each message type handler reads uninitialized payload

and KMSAN detects this issue. The receipt of a packet with a zero-size

payload is considered unexpected, and therefore, such packets should be

silently discarded.

This patch resolved this issue by checking payload size before calling

each message type handler codes.

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.
