CVE-2023-54076 Details
Description
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix missed ses refcounting Use new cifs_smb_ses_inc_refcount() helper to get an active reference of @ses and @ses->dfs_root_ses (if set). This will prevent @ses->dfs_root_ses of being put in the next call to cifs_put_smb_ses() and thus potentially causing an use-after-free bug.
A use-after-free vulnerability has been addressed in the Linux kernel's SMB client. The issue arose from improper session reference counting, particularly with DFS root sessions. When a session was not correctly referenced, it could lead to a use-after-free condition, potentially causing memory corruption or other unintended behavior. This vulnerability affects the Linux kernel's stable releases.
