kernel_range: refresh tables from Debian tracker — 5 MISSING adds + 4 off-by-one harmonisations
First batch of fixes surfaced by tools/refresh-kernel-ranges.py.
Drift drops from 18 actionable findings (5 MISSING + 13 TOO_TIGHT)
to 13 (now only 1 MISSING + 12 TOO_TIGHT). The remaining
TOO_TIGHT findings all involve threshold-version drops of 2+
patch versions; those need per-commit verification against
git.kernel.org/linus before applying (saving for a follow-up).
MISSING adds — branches Debian has fixed that we had no entry for:
af_unix_gc (CVE-2023-4622):
+ {6, 4, 13} stable 6.4.x (forky/sid/trixie all at this version)
dirtydecrypt (CVE-2026-31635):
+ {6, 19, 13} stable 6.19.x (forky/sid) — our previous table
only listed mainline 7.0.0; Debian is shipping
the fix on the 6.19 branch ahead of 7.0 release.
overlayfs_setuid (CVE-2023-0386):
+ {5, 10, 179} stable 5.10.x (bullseye)
vmwgfx (CVE-2023-2008):
+ {5, 10, 127} stable 5.10.x (bullseye)
+ {5, 18, 14} stable 5.18.x (bookworm/forky/sid/trixie)
TOO_TIGHT harmonisations — single-patch-version differences,
almost certainly off-by-one curation errors on our side:
nf_tables (CVE-2024-1086):
{5, 10, 210} -> {5, 10, 209} (Debian bullseye)
nft_payload (CVE-2023-0179):
{5, 10, 163} -> {5, 10, 162} (Debian bullseye)
nft_set_uaf (CVE-2023-32233):
{5, 10, 180} -> {5, 10, 179} (Debian bullseye)
{6, 1, 28} -> {6, 1, 27} (Debian bookworm)
Larger TOO_TIGHT diffs deferred:
- cgroup_release_agent (5.16.9 -> 5.16.7, diff 2)
- cls_route4 (5.18.18 -> 5.18.16, diff 2; 5.10.143 -> 5.10.136, diff 7)
- dirty_cow (4.7.10 -> 4.7.8, diff 2)
- dirty_pipe (5.10.102 -> 5.10.92, diff 10)
- netfilter_xtcompat (5.10.46 -> 5.10.38, diff 8)
- overlayfs_setuid (6.1.27 -> 6.1.11, diff 16)
- ptrace_traceme (4.19.58 -> 4.19.37, diff 21)
- sequoia (5.10.52 -> 5.10.46, diff 6)
These need per-commit confirmation against the upstream-stable
kernel changelog before lowering our threshold. Conservatively
keeping the current (more strict) values until each is verified.
Verification:
- Linux (docker gcc:latest + libglib2.0-dev + sudo): 44/44 tests
pass, full build clean.
- macOS (local): 31-module build clean.
- tools/refresh-kernel-ranges.py rerun: drift reduced 18 -> 13.
