BELL-CVE-2026-74273

Affected: Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

EUVD-2026-353804

fkie_cve-2026-74273

In the Linux kernel, the following vulnerability has been resolved:

cxl/region: Block region delete during region creation

Expand the range lock, rename it "regions_lock", to disable region deletion in the critical period between construct_region() and attach_target(), as well as the period between device_add() and registering the remove actions.

Otherwise, userspace can confuse the kernel. It can violate the assumption the region stays registered through the completion of cxl_add_to_region(). It can violate the assumption that devm_add_action_or_reset() is working with a live 'struct cxl_region'.

It is ok for the region to disappear outside of those windows as that mirrors device hotplug flows where the proper locks are held.
