 ## Vulnerable Application
 
-This module exploits a vulnerability in the Linux Kernel's watch_queue event notification system. It relies on a heap
-out-of-bounds write in kernel memory. The exploit fails occasionally, but it does not crash the target and can be run
-multiple times until privilege escalation is achieved.
+This module exploits a vulnerability in the Linux Kernel's watch_queue event
+notification system. It relies on a heap out-of-bounds write in kernel memory.
+The exploit may fail on the first attempt so multiple attempts may be needed.
+Note that the exploit can potentially cause a denial of service if multiple
+failed attemps occur, however this is unlikely.
