Methodology for discovering and exploiting Linux kernel memory-corruption vulnerabilities (UAF, OOB read/write, race/TOCTOU, type confusion) during authorized engagements, covering reachability analysis, building stable read/write primitives from a single bug, defeating KASLR/SMEP/SMAP/KPTI, slab/buddy heap grooming, and pivoting to ring-0 code execution or credential overwrite for local privilege escalation.

# Exploiting Linux Kernel Vulnerabilities

## When to Use

- During authorized kernel security assessments, local privilege-escalation (LPE) research, or sandbox-escape work where
  unprivileged userland can reach kernel code through a syscall, ioctl, socket family, netlink, or a vulnerable driver.
- When triaging a kernel crash (`Oops`, `KASAN` splat, `GENERAL PROTECTION fault`, `BUG: KASAN: use-after-free`) and you
  need to determine whether the bug is a controllable UAF, OOB, double-free, or race rather than a pure null-deref DoS.
- When a recent CVE (e.g., AF_UNIX `MSG_OOB` UAF / CVE-2025-38236, POSIX CPU-timers TOCTOU / CVE-2025-38352, ksmbd
  OOB write / CVE-2025-37947) is in scope and you must confirm reachability and exploitability on the target build.
- As the methodology that turns a weak kernel primitive (a 1-byte read, a `+N` increment, a single freed object) into
  full kernel read/write/execute.
