In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Do not register event handler until srpt device is fully setup
Upon rare occasions, KASAN reports a use-after-free Write in
srpt_refresh_port(). This seems to be because an event handler is
registered before the srpt device is fully setup and a race condition upon
error may leave a partially setup event handler in place. Instead, only
register the event handler after srpt device initialization is complete.

Notes

Author	Note
	Priority reason: Exploitation requires device initialization, which requires either physical access or privileged access.
