php-8.0.30-8.el9_8.ML.1

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP
Server.

Security Fix(es):
* 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.

CVE-2026-109618
PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context
and abort handling of the request. Some contexts may not properly account for
this scenario and leave request memory in an uninitialized state before
performing an allocation. The subsequent request cleanup procedure may read or
branch on this memory. Multiple OOM strategies can consistently trigger this
condition and lead to remote code execution (RCE).
CVE-2026-109619
PHP has various global state that temporarily points into request memory. In
some scenarios, global state may not be correctly reset, or may be repopulated
after being reset. The global state may then refer to request memory even after
it has been freed. Subsequent requests may read or branch on this stale state
before it is fully initialized. Multiple strategies can trigger this condition
and produce remote code execution (RCE).
