Overview

Affected versions of this package are vulnerable to Use After Free in the __close_file_table_ids process. An attacker can achieve remote code execution or cause a denial of service by exploiting a race condition between file close and rename operations over an authenticated SMB session, leading to use of a freed object in kernel memory.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
