About this tag
KASLR (Kernel Address Space Layout Randomization) is a Windows security mitigation designed to prevent attackers from predicting the location of kernel objects in memory. Discussions on WindowsForum.com cover recent vulnerabilities that bypass or weaken KASLR, including CVE-2025-53136, a TOCTOU information disclosure in the Windows kernel that leaks kernel addresses, and cache timing side-channel attacks that break KASLR on Windows 11. Other threads address related kernel memory disclosure flaws such as CVE-2025-53803 and CVE-2025-32722, which can expose sensitive kernel data and aid privilege escalation. These topics highlight ongoing challenges in maintaining KASLR effectiveness against evolving local and side-channel attack techniques.
