CVE-2024-44962

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading

When unload the btnxpuart driver, its associated timer will be deleted.
If the timer happens to be modified at this moment, it leads to the
kernel call this timer even after the driver unloaded, resulting in
kernel panic.
Use timer_shutdown_sync() instead of del_timer_sync() to prevent rearming.
