CVE-2026-72212

A flaw was found in the Linux kernel's memory hotplug subsystem. An error in the memory cleanup process, specifically when memory is added and then an issue occurs during device creation, can lead to incorrect handling of memory pages. This vulnerability can result in memory corruption, potential...

CVE-2026-72172

A flaw was found in the Linux kernel. When Direct Access DAX memory is hotplugged, certain internal memory structures struct pages may not be fully initialized. This uninitialized state can lead to unexpected system behavior or crashes, potentially resulting in a denial of service...

CVE-2026-72172

CVE-2026-72172 affects the Linux kernel, specifically the mm/mm_init path related to ZONE_DEVICE. The issue occurs when DAX memory is hotplugged into an unoccupied subsection of an early section, causing section_activate() to reuse the boot memmap while compound_nr_pages() assumes vmemmap optimiz...

PT-2026-72360

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the memory management initialization where section activate reuses the unoptimized boot memmap when DAX memory is hotplugged into an unoccupied subsection of an early...

PT-2026-72400

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the create altmaps and memory blocks function where arch remove memory is called with a NULL altmap instead of params.altmap when create memory block devices fails whi...

CVE-2026-64295

A flaw was found in the Linux kernel's memory management mm component, specifically within the pageext iteration application programming interface API. When memory is dynamically added to the system a process known as 'hotplugging', the API does not properly validate memory page frame numbers PFN...

Siemens SIMATIC S7-1500 CPU 1518 MFP Race Condition within a Thread (CVE-2025-38681)

In the Linux kernel, the following vulnerability has been resolved: mm/ptdump: take the memory hotplug lock inside ptdumpwalkpgd Memory hot remove unmaps and tears down various kernel page table regions as required. The ptdump code can race with concurrent modifications of the kernel page tables...
