Astra Linux – vulnerability in linux-6.18

In the Linux kernel, the following vulnerability has been resolved: schedext: Derive SCXRQINWAKEUP from the core enqueue flags scheduledeferredlocked skips scheduling a deferred action while SCXRQINWAKEUP is set; it relies on the taskwokenscx call that follows a wakeup enqueue to run it...

CVE-2026-99269

A flaw was found in the Linux kernel's schedext extensible scheduler subsystem. A race condition exists when moving tasks off dispatch queues because the consume and move paths do not wait for the dispatch operation to finish. A local user could exploit this timing issue to cause concurrent task...

CVE-2026-99269

The Linux kernel is affected by a vulnerability in sched_ext where a task can be found on a non-local DSQ while the dispatching CPU is still executing ops.dequeue() and has not yet cleared SCX_OPSS_DISPATCHING . This occurs because the DSQ consume and move paths do not wait for the dispatch to fi...

Linux Distros Unpatched Vulnerability : CVE-2026-99269

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Wait for SCXOPSSDISPATCHING before moving tasks off DSQs A task can be found on a non-local DSQ while the CPU which dispatched it is still running...

CVE-2026-98942

A flaw was found in the Linux kernel's schedext extensible scheduler subsystem. Due to a race condition, internal core-ID mapping tables were exposed before being fully initialized and were modified without adequate synchronization. A local attacker could exploit this timing issue during schedule...

CVE-2026-99144

A flaw was found in the Linux kernel's schedext extensible scheduler component. A race condition during the destruction of a user dispatch queue allows a deferred task re-enqueue operation to access memory that has already been freed. A local user can exploit this use-after-free vulnerability to...

CVE-2026-99105

A flaw was found in the Linux kernel's schedext scheduler component. When a task is placed back onto a CPU's local dispatch queue under specific scheduler configurations, the kernel fails to reschedule the CPU, causing it to idle while tasks wait to execute. A local user can trigger this conditio...

CVE-2026-99104

A flaw was found in the Linux kernel's extensible scheduler schedext subsystem. This vulnerability allows a local user to cause a denial of service DoS or system instability during power management operations. Due to improper tracking of bypass dispatch states across hierarchical schedulers durin...

CVE-2026-99144

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix use-after-free of a destroyed user DSQ by a deferred reenqueue A deferred reenqueue can read a freed user DSQ. The request stays on its CPU's deferred list until rundeferred takes it, and the RCU callback that frees...
