Hi Greg, Sasha, and maintainers, I'm working through the smaller CVE backports still missing from 6.6.y. These 2 upstream changes belong together for CVE-2025-21976. 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. These fixes also affect 6.1.y, which will need a separate backport; this series is only for 6.6.y. Could you please consider this series for 6.6.y? Thanks, Artem Dinaburg Series: 1. fbdev: hyperv_fb: Simplify hvfb_putmem 2. fbdev: hyperv_fb: Allow graceful removal of framebuffer base: v6.6.157 (79643295eba17affbd16ca97f3ef04c90266b28c) plus stable-queue revision 958ddf240a33ef26b1771be944f0ea6c3b597472
