KASLR
Kernel Address Space Layout Randomization, a security mitigation mechanism that randomizes the in-memory locations of kernel code and data, used to increase the difficulty of exploitation.
Timeline (last 90 days)
In kernel scenarios, successfully exploiting a vulnerability requires breaking through multiple layers of mitigations such as KASLR, SMEP, SMAP, and stack protection, and often requires building a complete exploit chain with techniques such as heap spraying, ROP, or data-oriented attacks.
Writing a kernel exploit requires understanding the target kernel's memory layout, SLAB/SLUB allocator behavior, KASLR (kernel address space layout randomization), hardware mitigation mechanisms such as SMEP/SMAP, and designing a stable exploit chain for the specific vulnerability type (such as out-of-bounds write, UAF, or race condition).
