Security hardening and snapshot refresh. Linux 6.19 is upstream EOL. Move to the 6.12 LTS line via the trixie-security pocket, which carries Debian-backported fixes for four recent kernel CVEs: - CVE-2026-31431 (copy.fail / algif_aead) -- crypto: algif_aead - Revert to operating out-of-place (in 6.12.85-1). - CVE-2026-46300 (Fragnesia / XFRM ESP-in-TCP) -- xfrm: esp: avoid in-place decrypt on shared skb frags (Debian cherry-pick added in 6.12.86-1). - "Dirty Frag" / Copy Fail 2 -- same xfrm-esp shared-frag series; covered by the same cherry-pick. - CVE-2026-46333 (ssh-keysign-pwn / __ptrace_may_access dumpable) -- ptrace: slightly saner 'get_dumpable()' logic (in 6.12.88-1). Resulting package: linux 6.12.88-1 from trixie-security. Snapshot: 20260519T000413Z (latest debian-security snapshot confirmed to contain 6.12.88-1; same timestamp resolves on the main debian archive). Changes: - shared/mkosi.conf: KERNEL_VERSION 6.19 -> 6.12. - shared/mkosi.build.d/10-kernel.sh: drop the /trixie-backports suite pin from the apt-get install; 6.12 lives in main + security, not backports. - shared/mkosi.sync.d/10-setup-apt.sh: emit a second sources block for trixie-security (snapshot mirror archive/debian-security/, or security.debian.org for unpinned builds). - images/{flashbox-l1,flashbox-l2,l2-op-rbuilder,l2-op-rbuilder-bproxy, l2-simulator}.conf: Snapshot bumped to 20260519T000413Z.

perhaps not a "bump" but rather roll-back? |
