Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/gpusvm: fixed the usage of hmmpfntomaporder Handled the case where the hmm range partially covers a large page such as 2M. Otherwise, we might end up doing something unpleasant, such as mapping memory that is outside the...

SUSE CVE-2025-40336

In the Linux kernel, the following vulnerability has been resolved: drm/gpusvm: fix hmmpfntomaporder usage Handle the case where the hmm range partially covers a huge page like 2M, otherwise we can potentially end up doing something nasty like mapping memory which is outside the range, and maybe...

CVE-2025-40336

Vulnerability summary: CVE-2025-40336 affects the Linux kernel DRM/GPU virtualization path (drm/gpusvm). The root cause is incorrect usage of hmm_pfn_to_map_order when a memory range partially covers a huge page (e.g., 2 MiB), which could lead to mapping memory outside the intended range. The pat...

Unity Linux 20.1070e Security Update: kernel (UTSA-2025-414651)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-414651 advisory. An issue was discovered in Linux: KVM through Improper handling of VMIO|VMPFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still...

AZL-68690 CVE-2022-49562 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use trycmpxchguser to update guest PTE A/D bits Use the recently introduced trycmpxchguser to update guest PTE A/D bits instead of mapping the PTE into kernel address space. The VMPFNMAP path is broken as it assumes tha...

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap) a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks

A flaw was found in the Linux kernel’s KVM implementation, where improper handing of the VMIO|VMPFNMAP VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest. This flaw allows users who can start and control a VM to read/write random pages of...
