CVE-2026-10635

On Xtensa targets with CONFIGUSERSPACE and CONFIGXTENSAMMU, the page-table code arch/xtensa/core/ptables.c maintains a global list, xtensadomainlist, of active memory domains using a list node embedded inside the caller-owned struct kmemdomain. When a domain is destroyed via kmemdomaindeinit -...

CVE-2026-10635

CVE-2026-10635 affects Zephyr v4.4.0 on Xtensa targets with CONFIG_USERSPACE and CONFIG_XTENSA_MMU. The bug arises when destroying a memory domain via k_mem_domain_deinit(): the page-table code keeps a global xtensa_domain_list entry for the domain, but the node is not removed, leaving a dangling...
