CVE-2026-68090

The CVE-2026-68090 issue affects the Linux kernel debugobjects in the debug_object_assert_init() and debug_object_activate() paths, where a concurrent out-of-memory (OOM) scenario disables debug objects and frees shadow objects. As a result, a timer callback (stub_timer) may be invoked for an obj...
