RLSA-2026:98609: Important: php8.4 security update

Published Nov 13, 2026
·
Updated

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts.

Security Fix(es):

php: php: Denial of Service via unbounded recursion in SOAP parser (CVE-2026-91765)

php: OOM bailout during request parsing leads to memory corruption and RCE (CVE-2026-109618)

php: fatal error handling retains stale request state leading to use-after-free (CVE-2026-109619)

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.

Frequently Asked Questions

1

Which installed components are identified as affected by this advisory?

The advisory lists Rocky Linux php8.4-common and its debuginfo package, along with debuginfo packages for PDO, intl, opcache, GMP, SOAP, and LDAP. The listed fixes address issues in PHP request parsing, fatal-error handling, and the SOAP parser.

2

Can these issues be exploited remotely without authentication?

The provided vector for the high-severity rating is AV:N/AC:H/PR:N/UI:N. This indicates network reachability with no privileges or user interaction required, but exploitation has high attack complexity.

3

What security impacts are addressed by the update?

The update addresses a SOAP-parser denial of service, memory corruption that can lead to remote code execution during request parsing, and a use-after-free caused by stale request state after fatal-error handling. The supplied CVSS vector indicates high confidentiality, integrity, and availability impact.
