* It is possible to bypass HTTPS in the modal browser, if you reply to the HTTPS CONNECT with a standard HTTP 1.1 response, instead of attempting to create a tunnel. The browser will just display that response. The downside to this is you have no idea what the contents of even the HTTP REQUEST would have been, but it is useful for directing the web browser to any website you want. | * It is possible to bypass HTTPS in the modal browser, if you reply to the HTTPS CONNECT with a standard HTTP 1.1 response, instead of attempting to create a tunnel.

Not exploited yet because even though there is ChendoChap's method to execute usermode code in WebKit, there is no PS5 kernel dump to build a kernel ROP chain. Exploiting this kernel vulnerability blind is almost impossible because once the USB device is inserted it corrupts the kernel heap memory and if offsets are bad it creates a kernel panic. | |||

A SMAP bypass has been found by m00nbsd while working on FreeBSD 12. It is named CVE-2021-29628 and affects FreeBSD 12.2 and later (til it was patched). It does not work on PS4 because PS4 kernel is based on FreeBSD 9 which did not contain the vulnerability and because PS4 SMAP is not coming from FreeBSD but is custom from Sony. It used to work on PS5 before it was disclosed and patched. | |||
