In the Linux kernel, the following vulnerability has been resolved: USB: iowarrior: fix use-after-free on disconnect Submitted write URBs are not stopped on close() and therefore need to be stopped unconditionally on disconnect() to avoid use-after-free in the completion handler.

A flaw was found in the Linux kernel's USB iowarrior driver. This vulnerability, a use-after-free, occurs because write operations are not properly halted when a device disconnects. An attacker could potentially exploit this to cause system instability or execute arbitrary code.
