kernel: PCI/sysfs: Add lockdown checks to legacy I/O and memory handlers

A flaw was found in the Linux kernel's PCI/sysfs legacy I/O and memory handlers. These handlers failed to enforce kernel lockdown, a security mechanism designed to prevent privileged users from performing certain low-level operations. A local root user could exploit this by writing to arbitrary I...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: mm/vmemmap/devdax: fix kernel crash when probing devdax devices The commit 4917f55b4ef9 “mm/sparse-vmemmap: improve memory savings for compound devmaps” added support for using optimized vmmemap for devdax devices. However, how...

CVE-2026-98949

A flaw was found in the Linux kernel's Imagination PowerVR graphics driver. When splitting overlapping virtual memory mappings, the driver fails to release memory references and improperly links buffer objects. A local user can exploit this vulnerability by submitting crafted memory mapping...

CVE-2026-99208

A flaw was found in the Linux kernel's Intel Xe graphics driver. It allows information disclosure because memory buffers allocated for observation architecture OA streams are not cleared before being made accessible to user space. A local user can exploit this vulnerability by memory-mapping the...

DEBIAN-CVE-2026-99159

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix the sub-buffer array base in rbmetasubbufidx On a persistent ring buffer, rbmetasubbufidx can return an index one sub-buffer too high. rbsetupidsmetapage then fills subbufids shifted by one and leaves subbufids0...

Linux Distros Unpatched Vulnerability : CVE-2026-99159

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ring-buffer: Fix the sub-buffer array base in rbmetasubbufidx On a persistent ring buffer, rbmetasubbufidx can return an index one sub-buffer too high...

CVE-2026-98522

A flaw was found in the Linux kernel's Imagination PowerVR GPU driver. This vulnerability allows a local user to cause a Denial of Service DoS by crashing the system. The issue occurs when the driver fails to properly return an error code after a memory mapping failure, allowing execution to...

CVE-2026-98653

The Linux kernel contains a vulnerability within the KVM s390 subsystem. Specifically, in certain circumstances, a page of nested guest memory being shadowed may be missing from the parent guest gmap . This causes dat_entry_walk() to fail to find a leaf entry and return -ENOENT , which is then er...
