Preliminary research

Melting the Flesh of PHP's Memory Hardening

AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.

PHP's heap hardening initiative set out to stop popular heap exploitation techniques. The first security study of it finds the mitigations defeat current-generation exploits but not adapted ones: it names the flaw that lets specific mitigations be bypassed and gives new strategies generic across built-in PHP objects from an out-of-bounds write or use-after-free - even a single-byte overflow.
