CVE-2023-54260 Details
Description
In the Linux kernel, the following vulnerability has been resolved: cifs: Fix lost destroy smbd connection when MR allocate failed If the MR allocate failed, the smb direct connection info is NULL, then smbd_destroy() will directly return, then the connection info will be leaked. Let's set the smb direct connection info to the server before call smbd_destroy().
A vulnerability in the Linux kernel's CIFS (Common Internet File System) implementation has been addressed. The issue arose when the memory registration (MR) allocation failed, leaving the SMB direct connection information null. Consequently, the 'smbd_destroy()' function would return immediately, leading to a leak of the connection information. The vulnerability has been fixed by ensuring that the SMB direct connection information is set to the server before calling 'smbd_destroy()'.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version can be found in the Linux kernel official documentation.
