Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the ksmbd module. Specifically, a use-after-free condition can occur in the
ksmbd tree connect put function under conditions of high concurrency. This happens when a tree-connection object (tcon) is freed during a disconnect process while another process still holds a reference to it and attempts to operate on it.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
