Red Hat Security Advisory: rsync security update
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: Out of bounds array access via negative index (CVE-2025-10158) * 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.

Technical Summary
The rsync utility in Red Hat Enterprise Linux 10.0 Extended Update Support contains two security vulnerabilities: CVE-2025-10158, an out-of-bounds array access via a negative index, and CVE-2026-41035, a use-after-free vulnerability in extended attribute handling. These vulnerabilities could lead to memory corruption or other unintended behavior. Red Hat has issued security advisories and updated packages (rsync-3.4.1-2.el10_0.2) to fix these issues across multiple architectures including x86_64, s390x, ppc64le, and aarch64. The advisory rates the impact as Important and provides instructions for applying the update. No CVSS score is provided in the advisory.
Potential Impact
The vulnerabilities could allow an attacker to cause out-of-bounds memory access or use-after-free conditions in the rsync utility, potentially leading to crashes or memory corruption. This could affect the reliability and security of systems using rsync for file synchronization or mirroring. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated rsync packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 10.0 Extended Update Support should apply the security update rsync-3.4.1-2.el10_0.2 or later as provided by Red Hat. Refer to the Red Hat advisory RHSA-2026:20696 and the article https://access.redhat.com/articles/11258 for detailed update instructions. No additional mitigation steps are indicated by the vendor.
