CVE-2022-50351 Details
Description
In the Linux kernel, the following vulnerability has been resolved: cifs: Fix xid leak in cifs_create() If the cifs already shutdown, we should free the xid before return, otherwise, the xid will be leaked.
A vulnerability in the Linux kernel's CIFS (Common Internet File System) implementation has been identified, specifically in the cifs_create function. This vulnerability involves an XID (transaction ID) leak that occurs when CIFS is already shut down. In such cases, the XID should be freed before the function returns; otherwise, it will be leaked. The issue has been addressed in the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation.
