**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A memory leak exists in the smb2 open file() function within the SMB/client component of the Linux kernel. The issue occurs when directories are exported as read-only, and a CIFS mount is used with direct writes. Specifically, the reproducer involves mounting a read-only export, writing to a file, unmounting, and then removing the CIFS module, which can lead to objects remaining on the ` kmem cache shutdown()` resulting in a memory leak. The error message indicates a problem with the `kmem cache destroy` function and objects remaining in the `cifs small rq` slab cache. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
