Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel’s CIFS implementation related to session state handling during reconnection attempts. Specifically, the issue involves not properly releasing exiting sessions in the smb2 reconnect server() function, potentially leading to a use-after-free condition. The vulnerability occurs because exiting sessions are not immediately removed from the server’s session list, and can be accessed after they have been released.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
