New module for Qualys's 2026-05-20 disclosure: a __ptrace_may_access logic flaw leaves a process dropping privileges briefly reachable past its dumpable boundary; pidfd_getfd(2) steals root-opened fds / authenticated channels from it. Default-distro, no userns, arch-agnostic (fd-steal, no shellcode). detect(): version-pinned, predates-gate at pidfd_getfd's 5.6 introduction; kernel_range from Debian backports (5.10.251/6.1.172/6.12.88/7.0.7), drift-check clean. exploit(): spawns a setuid victim, pidfd_open()s it, sweeps pidfd_getfd() over its fd table during the cred-drop window, reports any uid-0-owned fd captured from a non-root context. Honest EXPLOIT_FAIL without a euid-0 witness; not yet VM-verified. mitigate(): yama ptrace_scope=2; cleanup() reverts. auditd/sigma/falco rules, NOTICE.md (Qualys TRU credit) + MODULE.md, safety rank 84. Wiring: registry, Makefile, cve_metadata (+JSON source), verify-vm/targets.yaml (ubuntu2204 + mainline 5.15.5 target, sweep pending). Docs: README + CVES.md + docs/index.html counts 39->40 modules / 34->35 CVEs; added to not-yet-verified lists + corpus pill.

* SKELETONKEY — canonical "register every module family" enumeration.
|
|
*
|
|
* Kept in its own translation unit so registry.c stays standalone:
|
|
* the kernel_range unit-test binary links registry.c (for the basic
|
|
* register / count / find API) without pulling in every module's
|
|
* symbol. The main binary and detect-integration test link this
|
|
* file too and get the full lineup.
|
|
*
|
|
* Adding a new module is one new register_<family>() declaration in
|
|
* registry.h plus one call below — the integration test picks it up
|
|
* via skeletonkey_register_all_modules() in its main().
