CVE-2026-68329 iommu/amd: Wait for completion instead of returning early in iommu_completion_wait()

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Wait for completion instead of returning early in iommucompletionwait needsync is a per-IOMMU flag shared by all domains and devices behind that IOMMU. It is set whenever a command is queued with sync == true and clear...

CVE-2026-68329

CVE-2026-68329 affects the Linux kernel’s iommu/amd path. A race in iommu_completion_wait() can cause it to return before all previously queued commands complete, enabling a use-after-free window where stale page-table translations may be used. The issue stems from need_sync being read locklessly...

CVE-2026-68325 iommu/amd: Bound the early ACPI HID map

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Bound the early ACPI HID map The ivrsacpihid command-line parser appends entries to a fixed four-element earlyacpihidmap array. Unlike the sibling IOAPIC and HPET parsers, it does not reject a fifth entry before...

CVE-2026-68325

The Linux kernel AMD IOMMU path (ivrs_acpihid parser) is affected by CVE-2026-68325. The parser appends entries to a fixed four-element early_acpihid_map and, unlike the IOAPIC/HPET parsers, does not reject a fifth entry before increasing the map size. The patch adds a capacity check at the commo...

CVE-2026-68275

The CVE-2026-68275 entry concerns the Linux kernel DRM/AMDGPU driver. In the AMDGPU GEM GET_MAPPING_INFO path, amdgpu_gem_op_ioctl() looks up the BO in the caller’s VM via amdgpu_vm_bo_find() but does not verify the returned pointer before using it. If no bo_va exists for the BO in that VM (the n...

CVE-2026-68256

Summary: CVE-2026-68256 affects the Linux kernel DRM/AMD Display stack, specifically the function detect_link_and_local_sink. The issue: on the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT, prev_sink is not released, whereas all other paths correctly call dc_sink_release(prev_sink). T...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: fix indefinite fence wait during GPU reset prereset only force-completes fences of MAPPED queues. A queue in any other state e.g. mid-eviction keeps its lastfence pending; after a GPU reset that fence never...

CVE-2026-68236 drm/amd/display: set new_stream to NULL after release

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: set newstream to NULL after release In dmupdatecrtcstate, the skipmodeset path releases newstream via dcstreamrelease but does not set the pointer to NULL.

CVE-2026-68236

CVE-2026-68236 : In the Linux kernel, the drm/amd/display path (dm_update_crtc_state) releases a stream pointer (new_stream) but fails to NULL it. If an error occurs later, the code may call dc_stream_release() again on the same dangling pointer, causing a double release and use-after-free. The f...

CVE-2026-68235

The CVE refers to drm/amd/display (dce100) in the Linux kernel. Root cause: when assigning a stream encoder for a second DisplayPort MST stream on DCE8-class ASICs, if the preferred digital encoder is already acquired, the code can fall back to an analog DAC encoder whose funcs table lacks DP hoo...
