Vulnerability from csaf_redhat - Published: 2026-10-02 09:04 - Updated: 2026-10-02 12:08

Summary

Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

Severity

Important

Scope

16 vulnerabilities in this advisory, including CVE-2026-56153.

CVE-2026-56153

A flaw was found in httpd's mod_charset_lite module. A heap-based buffer overflow (an out-of-bounds memory write) occurs in the finish_partial_char function when handling character set conversions. A remote attacker can exploit this flaw by sending specially crafted requests, leading to memory corruption. This issue primarily results in a Denial of Service (DoS) condition by crashing the server process.

7.5 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
