GHSA-XQ7V-GFW6-FJ88

Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-17 18:32

Details

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

wifi: ath12k: Avoid buffer overread in ath12k_wmi_op_rx()

Currently, in ath12k_wmi_op_rx(), the firmware buffer is read without first verifying that the buffer has enough data to hold a header. This could result in a buffer overread.

Update the logic to verify the buffer contains at least enough data to hold a wmi_cmd_hdr before reading from the buffer.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
