In the Linux kernel, the following vulnerabilities have been resolved: rcu-tasks: Fixed a race condition in the schedule function and the flush work operation. When booting secondary CPUs, cpusreadlock/unlock does not keep the online cpumask stable. This temporary change in the online mask result...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: sched/debug: The issue of dentry leaks during updatescheddomaindebugfs has been fixed. Kuyo reports that the pattern of using debugfsremovedebugfslookup causes a dentry leak. With a hotplug stress test, the machine eventually run...

SUSE CVE-2026-89598

In the Linux kernel, the following vulnerability has been resolved: fbdev: ssd1307fb: defer I2C transfers from damage callbacks The fbdev damage callbacks may run from fbcon while printk has disabled preemption. They currently update the display synchronously, which enters the sleeping I2C transf...

Linux Distros Unpatched Vulnerability : CVE-2026-89521

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sched/core: Handle picktask releasing the rq lock Core scheduling's picknexttask breaks when a -picktask implementation can release the rq lock. The selection...

Linux Distros Unpatched Vulnerability : CVE-2026-89519

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Replace SCXRQBALKEEP with a dispatch verdict return SCXRQBALKEEP tells the pick to keep running the previous task, a leftover from when balancing and...

Linux Distros Unpatched Vulnerability : CVE-2026-89520

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sched/core: Make core-sched flips wait for in-flight selections Core scheduling's picknexttask operates on all sibling rqs under one acquisition of the shared...

Linux Distros Unpatched Vulnerability : CVE-2026-89518

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Fix thisrq assumptions in dispatch kfuncs Under core scheduling, dispatch runs from within the core-wide pick and can target a sibling rq, so...

Linux Distros Unpatched Vulnerability : CVE-2026-89517

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Fix rq-corepick corruption under core scheduling Core scheduling's picknexttask picks what to run on every SMT sibling of the core in a single pass...

CVE-2026-89519

A flaw was found in the Linux kernel's schedext component. Due to a logical error where a stale flag SCXRQBALKEEP could be consumed, the scheduler might incorrectly keep a task running even after it has been dequeued. This could lead to unexpected task management behavior within the kernel...

CVE-2026-89580

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local attacker could exploit a timing issue in the bpfgetstack function. This occurs when a preemptible BPF program is scheduled out, allowing another task to overwrite a per-CPU buffer. This leads to an out-of-bounds...

CVE-2026-89520

A flaw was found in the Linux kernel's core scheduling component. A race condition can occur when core scheduling flips complete during task selection, leading to incorrect lock handling. This can result in a resource leak and system instability, potentially causing a denial of service...

CVE-2026-89517

A flaw was found in the Linux kernel's schedext component, which handles core scheduling. When multiple selections on the same core interleave due to a dropped lock, they can corrupt the scheduling state. This corruption can lead to a NULL dereference, tasks remaining active after being dequeued,...

CVE-2026-89521

A flaw was found in the Linux kernel's core scheduling component. This issue occurs when the picktask function releases the run queue rq lock, allowing an interleaving selection to invalidate the scheduler's internal state. This inconsistency can lead to incorrect task selection and skewed resour...

CVE-2026-89598

A flaw was found in the Linux kernel's fbdev framebuffer device subsystem, specifically within the ssd1307fb driver. This vulnerability occurs when display damage callbacks, which handle updates to the display, perform synchronous I2C Inter-Integrated Circuit transfers from an atomic context. Thi...

CVE-2026-89518

A flaw was found in the Linux kernel's schedext component. Under core scheduling, incorrect assumptions in dispatch kfuncs regarding thisrq can lead to a deadlock. This occurs when an rq lock is acquired on a CPU different from the dispatched rq's, potentially causing the system to become...
