CVE-2026-68265

CVE-2026-68265 affects the Linux kernel, specifically the drm/xe/vm path. The issue arises when prefetching a BO VMA in the region DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC, where the code uses the value as an index into region_to_mem_type[], causing an out-of-bounds access (value is -1). The remediatio...

CVE-2026-68265 drm/xe/vm: Fix BO prefetch with CONSULT_MEM_ADVISE_PREF_LOC

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: Fix BO prefetch with CONSULTMEMADVISEPREFLOC When prefetch region is DRMXECONSULTMEMADVISEPREFLOC for a BO VMA, the code used it as an index into regiontomemtype, causing an out-of-bounds access since the value is -1...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Avoid lock inversion when pinning to GGTT on CHV/BXT+VTD After i915vmapinww is completed, a synchronous variant of dmafenceworkcommit is called. When pinning a VMA to GGTT address space on a Cherry View family processor...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksm: The range-walk function is used to bypass holes in scangetnextrmapitem. Currently, scangetnextrmapitem walks every page address in a VMA to locate mergeable pages. This approach becomes highly inefficient when scanning large...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

CVE-2026-53373

A flaw was found in the Linux kernel's memory management mm/vma component. When the mmapprepare hook is invoked from an mmap operation, it can attempt to unmap a Virtual Memory Area VMA that is not fully established and already detached. This problematic behavior can lead to a warning in...

CVE-2026-64131

CVE-2026-64051 accel/qaic: Add overflow check to remap_pfn_range during mmap

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Add overflow check to remappfnrange during mmap The call to remappfnrange in qaicgemobjectmmap is susceptible to remapping beyond the VMA if the BO is too large. This can cause use after free issues when munmap unmaps...

CVE-2026-64051

The issue is in the Linux kernel’s accel/qaic driver. A bounds check was missing in remap_pfn_range called by qaic_gem_object_mmap, allowing (re)mapping beyond the VMA when the BO is large. This can yield use-after-free if munmap() only unmaps the VMA while extra mappings remain, enabling potenti...
