==== | ==== SMAP bypass method: CVE-2021-29628 ==== | ||
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 does not come from FreeBSD but is custom from Sony. It used to work on PS5 before it was disclosed and patched. | A SMAP bypass has been found by m00nbsd while working on FreeBSD 12.
