Does this matter?

Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.

A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work.
