Two moderate severity vulnerabilities were identified in the Apache HTTP Server mod_http2 module used in Red Hat Enterprise Linux 9 and 10. CVE-2026-48913 is a use-after-free vulnerability that could allow arbitrary code execution or denial of service. CVE-2026-43951 is an out-of-bounds read vulnerability in mod_headers and mod_mime. Red Hat has released patches addressing these issues in updated mod_http2 packages for affected RHEL versions.
