CVE-2026-46271 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: do WoW offloads only on primary link In case of multi-link connection, WCN7850 firmware crashes due to WoW offloads enabled on both primary and secondary links. Change to do it only on primary link to fix it. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
A vulnerability in the Linux kernel's handling of Wi-Fi offloads can lead to a crash in WCN7850 firmware. This issue arises in multi-link connections where offloads are enabled on both primary and secondary links. The vulnerability is present in the Linux kernel's stable branch, specifically in the Wi-Fi driver for the ath12k chipset, and affects WCN7850 hardware version 2.0.
The vulnerability has been addressed in a patch that modifies the WoW offload behavior to apply only on the primary link, preventing the firmware crash. This patch is available in the Linux kernel's stable branch.
