page_table_walk

Captura la Bandera en Memoria Física Has leído sobre paginación. Los diagramas tienen sentido. Cuatro niveles, 9 bits cada uno, marco de página, desplazamiento. Claro. Pero luego te encuentras con un desafío que requiere caminar realmente las tablas de páginas, y te das cuenta de que no lo sabes...

EUVD-2026-86245

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Fix the lockless page-table walk in showpte showpte walks page tables locklessly and can run with interrupts enabled. A concurrent teardown can free a table page while it is being walked. It can also clear a parent ent...

CVE-2026-93239

The Linux kernel (arm64 architecture) contains a vulnerability in the mm subsystem related to the lockless page-table walk in show_pte() . Because show_pte() walks page tables without holding locks and can run with interrupts enabled, a concurrent teardown can free a table page during the walk. A...

AZL-102504 CVE-2026-90383 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: misc: sgi-gru: remove interrupt-context page-table walks The GRU TLB miss handler walks a process's page tables without holding page-table locks or a reference to the mapped page. It also uses a kernel page-table accessor on user...

CVE-2026-90383

CVE-2026-90383 affects the Linux kernel's SGI GRU (General Register Unit) driver. The GRU TLB miss handler walks a process's page tables in interrupt context without holding page-table locks or a reference to the mapped page, and uses a kernel page-table accessor on user page tables, supporting o...

CVE-2026-90383: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: misc: sgi-gru: remove interrupt-context page-table walks The GRU TLB miss handler walks a process's page tables without holding page-table locks or a reference to the mapped page. It also uses a kernel page-table accessor on user...

kernel: KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation AT emulation, do not properly acquire a Sleepable Read-Copy Update...

SUSE CVE-2026-72358

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pt: prevent invalid cursor access for purged BOs During a page table walk for binding, xeptstagebind explicitly skips initializing the xerescursor for purged BOs, treating them similarly to NULL VMAs by only setting the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pt: A NULL pointer dereference occurred in xeptzapptesentry. The page-table walk framework might pass a NULL child pointer for unpopulated entries. The xeptzapptesentry function calls containerofchild before checking for...

CVE-2026-74524

A flaw was found in the Linux kernel. When performing memory hot-remove operations on systems using RISC-V architecture, an out-of-bounds page-table walk can occur. This issue arises because the system attempts to access memory outside of its designated boundaries, potentially leading to a kernel...

CVE-2026-72362

A flaw was found in the Linux kernel's drm/xe/pt module. This vulnerability arises when the page-table walk framework provides a null pointer for unpopulated entries, and the xeptzapptesentry function attempts to access this null pointer without prior validation. This improper handling can lead t...

CVE-2026-72358

A flaw was found in the Linux kernel's drm/xe/pt component. During page table walks for binding, specific functions xepthugeptepossible and xeptscan64K do not properly check if a Buffer Object BO has been purged. This oversight can lead to invalid access of an uninitialized cursor, potentially...
