Overview

CVE-2025-39732 is a high-severity vulnerability. It was published on September 7, 2025 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:

wifi: ath11k: fix sleeping-in-atomic in ath11k_mac_op_set_bitrate_mask()

ath11k_mac_disable_peer_fixed_rate() is passed as the iterator to

ieee80211_iterate_stations_atomic(). Note in this case the iterator is

required to be atomic, however ath11k_mac_disable_peer_fixed_rate() does

not follow it as it might sleep. Consequently below warning is seen:

BUG: sleeping function called from invalid context at wmi.c:304

Call Trace:

<TASK>

dump_stack_lvl

__might_resched.cold

ath11k_wmi_cmd_send

ath11k_wmi_set_peer_param

ath11k_mac_disable_peer_fixed_rate

ieee80211_iterate_stations_atomic

ath11k_mac_op_set_bitrate_mask.cold

Change to ieee80211_iterate_stations_mtx() to fix this issue.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30

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.
