Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: moving waitonsem out of the spinlock With iommu.strict=1, the existing completion wait mechanism can cause soft lockups in stressed environments. This occurs because waitonsem performs busy waits under a spinlock when...

Linux Distros Unpatched Vulnerability : CVE-2026-68117

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tipc: clear sock-sk on the failed-insert path in tipcskcreate When tipcskcreate fails to insert the new socket tipcskinsert returns non-zero, its error path...

CVE-2026-11742 Use-after-free race in kernel `k_queue_peek_head/tail` due to missing spinlock

The kernel queue helper zqueuenodepeek in kernel/queue.c dereferences a node taken from a queue's dataq list, reading the node's flag byte and, for items enqueued via kqueueallocappend/allocprepend, the data pointer of an internally allocated allocnode struct. The implementations of...

CVE-2026-11742

CVE-2026-11742 describes a use-after-free race in Zephyr’s kernel queue helpers: z_queue_node_peek() can dereference a node after another thread preempts or unlinks it via k_queue_get(), because peek operations weren’t protected by the queue spinlock. A concurrent consumer may free the node and i...

CVE-2026-64429

A flaw was found in the Linux kernel. The Spreadtrum EIC External Interrupt Controller driver incorrectly uses a standard spinlock in a critical interrupt handling path. When running on a PREEMPTRT Preemptible Real-Time kernel, this can cause the system to attempt to sleep in an invalid context...

CVE-2026-64292

A flaw was found in the Linux kernel's iommufd component. A local user can exploit this vulnerability by allocating large veventq queues, which are processed inside a spinlock. This can lead to the exhaustion of atomic memory reserves, resulting in a Denial of Service DoS condition...

SUSE CVE-2026-64292

In the Linux kernel, the following vulnerability has been resolved: iommufd: Move vevent memory allocation outside spinlock The veventq memory allocation happens inside the spinlock. Given its depth is decided by the user space, this leaves a vulnerability, where userspace can allocate large queu...
