Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to a use-after-free vulnerability in the ksmbd component of the Linux kernel. Specifically, the interim entry of ksmbd work could be deleted after an oplock is freed.
