Amazon Linux 2 (EOS) Security Advisory: ALAS2PHP8.2-2026-015
Advisory Released Date: 2026-10-22
Advisory Updated Date: 2026-10-22
FAQs regarding Amazon Linux ALAS/CVE Severity
A flaw was found in pcre2. When an application processes attacker-controlled regular expressions using certain Just-In-Time (JIT) compiler interfaces, an out-of-bounds write with arbitrary data can occur. An attacker could exploit this vulnerability to achieve arbitrary code execution, corrupt memory, or cause a denial of service (DoS). (CVE-2026-103111)
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-2026-109618)
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). (CVE-2026-109619)
