Researcher reports double-free in PHP 8.4.25, 8.5.10 and 8.5.12
Original title: Potential third critical PHP CVE
Elise sent PHP a short proof of concept; no CVE, patch, or vendor confirmation is stated.
On October 21, researcher Elise said AddressSanitizer reports a double-free in PHP 8.4.25 and that the issue still triggers on 8.5.10 and 8.5.12. She reported a three-line proof of concept to security@php.net and described it as a simple lifetime bug, distinct from other PHP issues discussed the same day. An encrypted backtrace is being held until a patch; she offered no mitigation beyond saying not to worry.
Unconfirmed: Only the researcher’s report; PHP has not confirmed a CVE, severity, or that the bug is exploitable.
- She says the bug is not the same as another PHP issue.
- The report asks PHP to test with ASAN and ZendMM disabled.
- A reply joking about preauth RCE is not her finding.
- No fixed PHP version is named.
