CVE-2026-31734

A flaw was found in the Linux kernel's schedext component. An incorrect check for migration-disabled tasks on systems without CONFIGPREEMPTRCU enabled could lead to a task being dispatched to a remote CPU. This can trigger an scxerror in taskcanrunonremoterq, resulting in a Denial of Service...

CVE-2026-31734

CVE-2026-31734 (Linux kernel sched_ext) has been fixed. The issue was a false negative where is_bpf_migration_disabled() could be incorrect on systems without CONFIG_PREEMPT_RCU, causing migration_disabled == 1 to be treated as truly migration-disabled even for the current task. The BPF prolog no...
