CVE-2024-39282
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
net: wwan: t7xx: Fix FSM command timeout issue
When driver processes the internal state change command, it use an asynchronous thread to process the command operation. If the main thread detects that the task has timed out, the asynchronous thread will panic when executing the completion notification because the main thread completion object has been released.
Use the reference counter to ensure safe release as Sergey suggests: https://lore.kernel.org/all/da90f64c-260a-4329-87bf-1f9ff20a5951@gmail.com/
