CVE-2025-68306
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: mediatek: Fix kernel crash when releasing mtk iso interface
When performing reset tests and encountering abnormal card drop issues that lead to a kernel crash, it is necessary to perform a null check before releasing resources to avoid attempting to release a null pointer.
