Like many other video game consoles, the PlayStation Portable is capable of photo, audio, and video playback in a variety of formats.However, unlike Sony's home consoles such as the PlayStation 3 and the PlayStation 4, it is not possible to play Blu-ray or DVD movies on the PlayStation Portable directly since it lacks a standard Blu-ray or DVD drive.
The kernel connects the application software to the hardware of a computer. Kernel Patch Protection (KPP), informally known as PatchGuard, is a feature of 64-bit editions of Microsoft Windows that prevents patching the kernel. It was first introduced in 2005 with the x64 editions of Windows Vista and Windows Server 2003 Service Pack 1. [1]
In January 2018, the Meltdown vulnerability was published, known to affect Intel's x86 CPUs and ARM Cortex-A75. [22] [23] It was a far more severe vulnerability than the KASLR bypass that KAISER originally intended to fix: It was found that contents of kernel memory could also be leaked, not just the locations of memory mappings, as previously thought.
After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
Kernel Patch Protection (KPP), a feature of 64-bit (x64) editions of Microsoft Windows that prevents patching the kernel, informally known as PatchGuard; kpatch, a feature of the Linux kernel that implements live patching of a running kernel; Ksplice, an extension of the Linux kernel that allows security patches to be applied to a running kernel
Soon after the PSP was released, hackers began to discover exploits in the PSP that could be used to run unsigned code on the device. Sony released version 1.51 of the PSP firmware in May 2005 to plug the holes that hackers were using to gain access to the device. [8] On 15 June 2005 the hackers distributed the cracked code of the PSP on the ...

Additionally, SMAP can expose flawed kernel code which does not follow the intended procedures for accessing user-space memory. [ 1 ] However, the use of SMAP in an operating system may lead to a larger kernel size and slower user-space memory accesses from supervisor code, because SMAP must be temporarily disabled any time supervisor code ...
