CVE-2026-112110
Description
A flaw was found in SafeNet Authentication Client (SAC). This vulnerability allows an authenticated local user to delete arbitrary files with elevated privileges by exploiting a time-of-check to time-of-use (TOCTOU) race condition in the SACSrv log-cleanup routine. By redirecting privileged file deletion operations outside the intended log directory, an attacker could compromise system integrity or cause a Denial of Service (DoS).
Statement
This vulnerability is rated as Moderate impact because exploitation requires pre-existing local system access and winning a tight timing window, while only permitting arbitrary file removal rather than direct arbitrary code execution or credential disclosure. SafeNet Authentication Client is proprietary third-party software provided by Thales and is not packaged or distributed across Red Hat supported products. Consequently, default installations of Red Hat Enterprise Linux and other Red Hat platforms are not impacted unless this standalone third-party security software has been manually introduced into the environment.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Integrity,Other
Technical Impact: Alter Execution Logic; Unexpected State
The attacker can gain access to otherwise unauthorized resources.
Integrity,Other
Technical Impact: Modify Application Data; Modify Files or Directories; Modify Memory; Other
Race conditions such as this kind may be employed to gain read or write access to resources which are not normally readable or writable by the user in question.
Integrity,Other
Technical Impact: Other
The resource in question, or other resources (through the corrupted one), may be changed in undesirable ways by a malicious user.
Non-Repudiation
Technical Impact: Hide Activities
If a file or other resource is written in this method, as opposed to in a valid way, logging of the activity may not occur.
Non-Repudiation,Other
Technical Impact: Other
In some cases it may be possible to delete files a malicious user might not otherwise have access to, such as log files.
Other
Technical Impact: Unexpected State
The product may perform invalid actions when the resource is in an unexpected state.
