Overview

CVE-2024-43847 is a high-severity vulnerability. It was published on August 17, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: ath12k: fix invalid memory access while processing fragmented packets

The monitor ring and the reo reinject ring share the same ring mask index.

When the driver receives an interrupt for the reo reinject ring, the

monitor ring is also processed, leading to invalid memory access. Since

monitor support is not yet enabled in ath12k, the ring mask for the monitor

ring should be removed.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00209-QCAHKSWPL_SILICONZ-1

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.
