These 2 upstream changes belong together for CVE-2025-68251, CVE-2026-53015. They must be applied in this order because the later change depends on or completes the earlier one. The complete series is already present in 6.12.y, 6.18.y, and 7.2.y. Patch 2 also affects 6.1.y and will need a separate backport; this series contains only the 6.6.y patches. Could you please consider this series for 6.6.y? Thanks, Artem Dinaburg Series: 1. erofs: avoid infinite loops due to corrupted subpage compact indexes 2. erofs: unify lcn as u64 for 32-bit platforms base: v6.6.157 (79643295eba17affbd16ca97f3ef04c90266b28c) plus stable-queue revision 958ddf240a33ef26b1771be944f0ea6c3b597472
