CVE-2026-68101

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. During the allocation or deallocation of a user pointer buffer object, a critical reference to its virtual memory object can become unavailable. This improper handling of memory submissions could lead to system instability or a denial ...

CVE-2026-68275

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: check amdgpuvmbofind result in GETMAPPINGINFO The AMDGPUGEMOPGETMAPPINGINFO path of amdgpugemopioctl looks up the bova for the buffer object in the caller's VM via amdgpuvmbofind, but uses the returned pointer without...

CVE-2026-68166

In the Linux kernel, the following vulnerability has been resolved: userfaultfd: prevent registration of special VMAs Vova Tokarev says: userfaultfd allows registration on shadow stack VMAs. With userfaultfd access, you can register on the shadow stack, discard a page ... and inject a page with...

CVE-2026-68275 drm/amdgpu: check amdgpu_vm_bo_find() result in GET_MAPPING_INFO

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: check amdgpuvmbofind result in GETMAPPINGINFO The AMDGPUGEMOPGETMAPPINGINFO path of amdgpugemopioctl looks up the bova for the buffer object in the caller's VM via amdgpuvmbofind, but uses the returned pointer without...

CVE-2026-68265

The CVE-2026-68265 entry concerns the Linux kernel DRM XE VM: a prefetch of a BO region (DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC) could be treated as an index into region_to_mem_type[], with the value -1 causing an out-of-bounds access. The fix resolves the preferred BO VMAs location directly: local V...

EUVD-2026-55482

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix check in amdgpuhmminvalidategfx For a short moment during alloc/free the userptr BO is not part of his VM, so bo-vmbo can be NULL. Keep a reference to the VM root PD as parent of the userptr BO so that we can alwa...

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 6.12

In the Linux kernel, the following vulnerability has been resolved: Tracing: The WARNON message in tracingbuffersmmapclose has been fixed for split VMA cases. When a VMA is split e.g., through partial munmap or MAPFIXED, the kernel calls vmops-close on each portion of the VMA. For trace buffer...

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...

TencentOS Server 3: dovecot (TSSA-2026:0810)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0810 advisory. Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:...

kernel: procfs: avoid fetching build ID while holding VMA lock

A deadlock vulnerability was found in the procfs PROCMAPQUERY ioctl handler. When fetching the optional build ID while holding the VMA lock mmaplock, a circular lock dependency can occur with the inode mutex, causing a system deadlock...

UBUNTU-CVE-2026-62429

Accessing the vNUMA configuration data of a guest is still possible when domain destruction has already started. The cleaning up of that configuration information is not synchronized with its retrieval by a device model controlling the guest...

kernel: futex: Drop CLONE_THREAD requirement for private default hash alloc

A flaw was found in the Linux kernel's futex subsystem. The needfutexhashallocatedefault function incorrectly relies on CLONETHREAD semantics, which can lead to non-concurrency issues when memory allocations mm-futexref pcpu allocations are shared across CLONEVM clones, excluding vfork. This can...
