modules: add nft_catchall (CVE-2026-23111, nf_tables catch-all abort UAF) 
The newest nftables LPE: a use-after-free in the nf_tables transaction-
abort path. An inverted condition (a stray '!') in
nft_map_catchall_activate() makes the abort path process active catch-all
map elements instead of skipping them; a catch-all GOTO element drives a
chain's use-count to zero so a following DELCHAIN frees it while the
catch-all verdict still references it -> UAF, escalatable from an
unprivileged user (userns + nftables) via modprobe_path/selinux_state ROP.
Fixed upstream by f41c5d1; CWE-416, CVSS 7.8; not in CISA KEV. Public
reproduction by FuzzingLabs.

Takes the corpus to 43 modules / 38 CVEs.

🟡 reconstructed trigger, primitive-only, NOT VM-verified — same contract
as nf_tables (CVE-2024-1086). detect() version-gates (catch-all elems
~5.13; Debian backports 6.1.164/6.12.73/6.18.10, 7.0+ inherits) AND
requires unprivileged user_ns clone (else PRECOND_FAIL). exploit() forks
an isolated child, builds a verdict map with a catch-all GOTO element,
provokes an aborting batch to drive the abort-path UAF, observes slabinfo,
and returns EXPLOIT_FAIL — the per-kernel leak + R/W + modprobe_path ROP
is not bundled. kernel_range table verified drift-clean against the live
Debian tracker (the 6.18 branch / 6.18.10 fix is the real forky/sid
backport; the earlier 7.0.10 figure was wrong).

Wired: registry, Makefile, safety rank (35), 6 detect() test rows (version
+ userns gating), CVE_METADATA.json + cve_metadata.c + KEV_CROSSREF.md
(sorted insert, CWE-416/T1068/not-KEV), README + CVES.md + website counts
(43/38) + yellow pill, RELEASE_NOTES v0.9.11, verify-vm target. Credit:
FuzzingLabs + upstream fix f41c5d1. Version 0.9.11.
