A kernel exploit is a program specially designed to trigger a flaw in kernel code and thereby gain the system's highest privileges (ring 0 or an equivalent privilege level); upon success, the attacker can bypass all of the operating system's permission checks, directly read and write arbitrary memory, tamper with the system call table, load unsigned modules, and even implant a persistent backdoor in the kernel.

UnverifiedKernel-level anti-cheat systems such as EasyAntiCheat, BattlEye, and Riot's Vanguard monitor process behavior at the operating system kernel level and may misidentify input-monitoring collection tools as cheats.77% similarUnverifiedEven if a user-mode program has a serious vulnerability, the impact is usually confined to that process; but once a kernel vulnerability is exploited, the attacker can obtain the system's highest privileges, and the scope of impact is the entire machine.73% similarUnverifiedA side-channel attack refers to an attack method that does not directly attack the cryptographic algorithm itself, but instead infers keys or sensitive data by analyzing physical information leaked during the system's computation process (such as power consumption, electromagnetic radiation, execution time and cache hit rates).72% similarUnverifiedLinux内核曾因编译器优化掉空指针检查而引入安全漏洞CVE-2009-189772% similarUnverifiedWriting 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).72% similar
