In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: wed: use proper wed reference in mt76 wed driver callabacks MT7996… (CVE-2025-68360)
A vulnerability in the Linux kernel's mt76 wireless driver (specifically the wed callbacks for MT7996 devices) causes a kernel crash due to improper handling of wed references when using wed_hif2 devices, such as on 6GHz links. The issue leads to a kernel read from an unreadable memory address, resulting in an internal error and system instability. This vulnerability has been resolved by fixing the detection of the proper wed reference in the driver callbacks.
AI Analysis
Technical Summary
The Linux kernel mt76 driver for MT7996 wireless devices supports offloading traffic using wed and wed_hif2 devices. The vulnerability arises because the driver code incorrectly assumes the use of the primary wed device in wed callbacks, which leads to a crash when the hardware runs wed_hif2 (e.g., on 6GHz links). This causes a kernel read from an invalid memory address, triggering a kernel oops and system crash. The fix involves correcting the detection and usage of the appropriate wed reference during these callbacks.
Potential Impact
Exploitation of this vulnerability results in a denial of service due to kernel crashes and system instability. There is no indication of confidentiality or integrity impact, but the availability of the affected system is severely impacted.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to properly detect and use the correct wed reference in the mt76 driver callbacks. Users should update to a Linux kernel version that includes this fix. Patch status is not explicitly confirmed in the provided data; therefore, check the vendor or Linux kernel advisory for the exact fixed version and apply the update accordingly.
