Q85 / 100
What is Kernel Address Space Layout Randomization (KASLR) and its limitations?
Correct! Well done.
Incorrect.
The correct answer is B) Randomizing the kernel's base address to make exploits harder — limited by info-leak vulnerabilities that reveal the actual address
B
Correct Answer
Randomizing the kernel's base address to make exploits harder — limited by info-leak vulnerabilities that reveal the actual address
Explanation
KASLR randomizes kernel base at boot, making hardcoded addresses fail. But side-channel attacks (KASLR bypass via TLB timing, prefetch timing) can leak the kernel address, negating protection. SMEP/SMAP provide complementary defenses.
