Vulnerability from csaf_redhat - Published: 2026-07-22 10:39 - Updated: 2026-07-28 16:32Summary
Red Hat Security Advisory: acl security update
Severity
Important
Notes
Topic: An update for acl is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: Access Control Lists (ACLs) are used to define fine-grained discretionary access rights for files and directories. The acl packages contain the getfacl and setfacl utilities needed for manipulating access control lists.
Security Fix(es):
* acl: Symlink traversal privilege escalation via libacl functions (CVE-2026-54369)
* acl: TOCTOU Symlink Traversal via getfacl/setfacl (CVE-2026-54370)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in the `acl` package, specifically within its `libacl` pathname-based functions. A local attacker could exploit this vulnerability by using a symbolic link to replace a pathname component. This could allow the attacker to redirect access control list (ACL) read or write operations to arbitrary files or directories, leading to unauthorized manipulation of ACLs and ultimately local privilege escalation.

Threats
Impact
Important
A time-of-check to time-of-use (TOCTOU) race condition vulnerability was found in `acl`. By replacing a pathname component with a symbolic link between a security check and subsequent file operations, an attacker can redirect file access control list operations. This occurs when privileged processes invoke `getfacl` or `setfacl` over an attacker-controlled path, potentially leading to local privilege escalation.
