has ways to achieve a softmod. They rely on WebKit vulnerabilities in the PS4 Web Browser combined with a kernel exploit. All models of PS4 can be softmodded. They are all tether exploits meaning they have to be performed every time the console is powered on, although some exploits may be persisted using rest mode. Softmodding a PS4 allows users to run homebrew, load game backups, bypass region checks, and change fan and CPU/GPU speeds. Some payloads can boot the PS4 into a Linux distribution, although this is not permanent and the console will revert to Orbis OS on reboot. Notable firmware revisions that result in a softmod are: 1.76, 4.05, 4.74, 5.05/5.07, 6.72, 7.02, 7.55, 9.00, with 5.05/5.07 being the most stable and 9.00 the most stable after that. It is worth noting unlike the other exploits, the 9.00 exploit requires inserting a specially crafted USB flash drive into the console. Softmods for PlayStation 5 The PlayStation 5 has ways to achieve a softmod. They rely on a userland exploit, which can be WebKit vulnerabilities in the PS5 Web Browser, or a specially crafted Blu-ray disc, combined with a kernel (and possibly hypervisor) exploit; depending on the kernel exploit used, may also require a specially crafted USB flash drive. The hypervisor exploit has not been publicly disclosed, however there are other known limited softmods consisting of a userland and kernel exploit which is heavily restricted in comparison. The limited softmods allows the install of PKGs (but not run them), start an FTP server, dump PS5 files, modify the PS4 backwards compatibility blacklist, as well as enabling the Debug Settings, where only a few of the debug options actually work. Compared to the previous generation console, a userland and kernel exploit would have been enough to accomplish what is generally regarded as a true jailbreak, however the PS5 has added security measures in comparison to the PS4, mainly a hypervisor and other restrictions such as execute only memory which makes reverse engineering much more difficult. The IPv6 kernel exploit (which led to the PS4 6.72 firmware jailbreak) was patched on the PS4 a few months prior to the release of the PS5, in which it was patched on the PS5 a while after, affecting PS5 firmware up to 4.51. The exFAT filesystem kernel exploit that affected PS4 firmware up to 9.00 also affected PS5 firmware up to 4.03. Firmware revisions
