kernel exploitation
About this tag
Discussions on WindowsForum.com cover kernel exploitation vulnerabilities affecting Windows systems, including elevation-of-privilege flaws in drivers like netbt.sys and cldflt.sys, use-after-free bugs in the Kernel Transaction Manager and Microsoft Brokering File System, and type-confusion in Win32K ICOMP. Additional threads examine KASLR bypass techniques using driver vulnerabilities and cache timing side-channel attacks that undermine kernel address space randomization. These topics are relevant for system administrators and security professionals focused on patching, mitigation, and detection of kernel-level exploits.
