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-2026-111115

Apache Kafka's code-generated readers for flexible protocol versions read a tagged-field count declared by the sender and retain a RawTaggedField object for each unknown field. That count was bounded only by the outer request frame size socket.request.max.bytes; it was not checked against the...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions 3.16.50 through 3.17 and 4.13. It arises because bcmgenet fails to perform unshare on shared skb prior to writing control blocks; as a result, subsequent transmissions overwrite lastcb. This causes bytes from previously completed slots to b...

Important: containerd

Issue Overview: containerd is an open-source container runtime. Prior to versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1, a crafted OCI index graph can force very high CPU/memory usage during PullImage before container start, causing long ContainerCreating stalls and, at larger sizes, node/runti...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.12. It arises because schedext fails to requeue tasks on the queue when the CPU goes offline; as a result, these tasks remain counted and cannot be awakened by hotplug threads, leading to CPU hotplug hangs or offline stalls...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 3.11. It arises because tipctopsrvstop closes subscriber connections while the send and receive work queues of the topology server are still active, potentially leading to use-after-free conditions, execution of queuework on already-destroye...

CVE-2026-98538

A flaw was found in the Linux kernel's writeback subsystem. This flaw allows a local user to cause a Denial of Service DoS by triggering prolonged processor stalls. When the kernel cleans up offline control group writeback structures with a large number of cached files, it repeatedly rescans...

Linux Distros Unpatched Vulnerability : CVE-2026-98549

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tcp: prevent collapsing skbs across boundary in rtx queue tcpwritecollapsefence sets TCPSKBCBskb-eor = 1 on tcpwritequeuetailsk to prevent skbs queued after a...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/vmwgfx: Fixed a deadlock in DMA buffer fence polling. A new version of the fence operations was introduced, which, upon release, does not remove the fences from the pending list. This eliminates the need for a lock to...
