CVE-2024-43847 Details
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
A vulnerability in the Linux kernel's ath12k Wi-Fi driver for Qualcomm Wi-Fi 7 devices has been addressed. The issue arose from the monitor ring and the reo reinject ring sharing the same ring mask index. When an interrupt for the reo reinject ring was received, it inadvertently processed the monitor ring, causing invalid memory access. Since monitor support is not yet active in ath12k, the monitor ring's mask should be removed. This vulnerability was present in the QCN9274 hardware version 2.0, under the PCI WLAN.WBE.1.1.1-00209-QCAHKSWPL_SILICONZ-1 release.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
