The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Fix SCXKICKWAIT deadlock by deferring wait to balance callback SCXKICKWAIT busy-waits in kickcpusirqworkfn using smpcondloadacquire until the target...

SUSE CVE-2026-43216

In the Linux kernel, the following vulnerability has been resolved: net: Drop the lock in skbmaytxtimestamp skbmaytxtimestamp may acquire sock::skcallbacklock. The lock must not be taken in IRQ context, only softirq is okay. A few drivers receive the timestamp via a dedicated interrupt and comple...

CVE-2026-43262

A flaw was found in the Linux kernel's gfs2 filesystem. This vulnerability occurs when the gfs2fiemap function calls iomapfiemap while holding an inode glock a global lock for filesystem operations. If the fiemap buffer is memory mapped to the same inode and accessing it triggers a page fault, it...

CVE-2026-43234

A flaw was found in the Linux kernel's team driver. A local user can exploit this vulnerability by manipulating network devices and namespaces. Specifically, when a slave device is unregistered from a team interface while a NETDEVCHANGEMTU event is pending, it can lead to a deadlock or resource...

CVE-2026-43216

A flaw was found in the Linux kernel's networking subsystem. Specifically, the skbmaytxtimestamp function can attempt to acquire a lock in an Interrupt Request IRQ context, which is an inappropriate execution environment for this operation. This can occur when certain network drivers process...

kernel: Linux kernel: Denial of Service due to a deadlock in hugetlb folio migration

A flaw was found in the Linux kernel. A local attacker could exploit a deadlock vulnerability due to incorrect lock ordering between foliolock and immaprwsem when migrating hugetlb file-backed folios. This could lead to hung tasks and potential system-wide stalls, resulting in a Denial of Service...

CVE-2026-43127

A flaw was found in the Linux kernel's ntfs3 component. This vulnerability involves a circular locking dependency, also known as an AB-BA deadlock, which can occur when the system attempts to acquire two specific locks in a conflicting order. This issue can cause the system to become unresponsive...
