In the Linux kernel, the following vulnerability has been resolved: rcv: move memblockallowresize after linear mapping is ready The initial memblock metadata is accessed from the kernel image mapping. The regions arrays need to be “reallocated” from memblock and accessed through linear mapping to...

Defeating KASLR by Doing Nothing at All

Posted by Seth Jenkins, Project Zero Introduction I've recently been researching Pixel kernel exploitation and as part of this research I found myself with an excellent arbitrary write primitive…but without a KASLR leak. As necessity is the mother of all invention, on a hunch, I started researchi...
