In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: add cancel_work_sync() for c2hcmd_work
The workqueue might still be running, when the driver is stopped. To
avoid a use-after-free, call cancel_work_sync() in rtl8xxxu_stop().
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: rtl8xxxu: agregue cancel_work_sync() para c2hcmd_work Es posible que la cola de trabajo aún esté ejecutándose cuando se detiene el controlador. Para evitar un use-after-free, llame a cancel_work_sync() en rtl8xxxu_stop().
A vulnerability was found in the Linux kernel's net rtl8xxxu_core.c driver, where a race condition can lead to a use-after-free situation in the rtl8xxxu_stop() function. This occurs when the workqueue is still running but the driver has been stopped and can lead to c2hcmd_work attempting to access memory that has been freed. This issue can lead to memory corruption or crashes.
