Doc Text:
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.
