Summary
It was discovered that PHP incorrectly handled out-of-memory conditions
while processing requests. A remote attacker could use this issue to
execute arbitrary code. (CVE-2026-109618)
It was discovered that PHP incorrectly managed internal request state
across worker reuse. A remote attacker could use this issue to execute
arbitrary code. (CVE-2026-109619)

Critical 9.2
RCE via OOM corruption
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 s…

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. Subs…
