Vulnerability from csaf_redhat - Published: 2026-05-19 16:27 - Updated: 2026-05-21 19:35Summary
Red Hat Security Advisory: rsync security update
Severity
Important
Notes
Topic: An update for rsync is now available for Red Hat Enterprise Linux 10.
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: The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool.
Security Fix(es):
* rsync: Rsync: Use-after-free vulnerability in extended attribute handling (CVE-2026-41035)
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 rsync. When rsync is configured to handle extended attributes (using the -X or --xattrs option), a remote attacker can exploit a use-after-free vulnerability. This occurs because the receive_xattr function incorrectly processes an untrusted length value during a sorting operation, leading to memory corruption. Successful exploitation can result in a denial of service, causing the rsync process to crash, and may potentially allow for arbitrary code execution.

This occurs because the receive_xattr function incorrectly processes an untrusted length value during a sorting operation, leading to memory corruption. Successful exploitation can result in a denial of service, causing the rsync process to crash, and may potentially allow for arbitrary code execution.",
