Details

In the Linux kernel, the following vulnerability has been resolved:

drm/pagemap: Prevent double migration of device pages

A device-private folio migrated to system memory by a CPU fault can remain reachable through the raw-PFN eviction path until migration finalization drops the source reference.

If eviction selects the same device-private folio during this window, it can attempt to migrate the folio again. The second migration can leave an uncharged folio on an LRU list, causing folio_lruvec_lock_irqsave() to retry indefinitely and resulting in a soft lockup and RCU stall.

Mark successfully migrated device-private folios using a low bit of their zone_device_data before migration finalization. Make both CPU-fault and raw-PFN migration paths skip device-private folios carrying this flag.

Mask the flag when retrieving the drm_pagemap_zdd pointer and preserve it when a device-private folio is split. Keeping the state on the physical folio also avoids depending on a virtual address that may change before a fault occurs.

v2: - Replace the retired-PFN XArray with an embedded bitmap. (Matthew Brost) - Mark every base page covered by a migrated folio so retirement remains valid if the folio is later split.

v3: - Store the migrated state in a low bit of zone_device_data instead of adding virtual-range and bitmap tracking to the ZDD. (Matthew Brost) - Mask the flag when retrieving the ZDD and preserve it when splitting a folio. - Drop the pre-existing fixes already covered by Matthew Brost's series: https://patchwork.freedesktop.org/series/171651/

v4: - Advance by the folio size only for migration entries marked with MIGRATE_PFN_COMPOUND. (Sashiko)

v5: - Simplify ZDD flag updates and folio iteration. (Matthew Brost) - Skip retired device-private folios in the CPU-fault path. (Matthew Brost) - Preserve flag bits while taking a new ZDD reference for split folios.

v6: - Restore MIGRATE_PFN_COMPOUND-aware stepping so non-compound migration entries are processed one at a time. (Sashiko) - Drop the pre-existing fixes already covered by Matthew Brost's series: https://patchwork.freedesktop.org/series/171651/

The second migration can leave\nan uncharged folio on an LRU list, causing folio_lruvec_lock_irqsave() to\nretry indefinitely and resulting in a soft lockup and RCU stall.\n\nMark successfully migrated device-private folios using a low bit of\ntheir zone_device_data before migration finalization. Make both CPU-fault\nand raw-PFN migration paths skip device-private folios carrying this\nflag.\n\nMask the flag when retrieving the drm_pagemap_zdd pointer and preserve\nit when a device-private folio is split. Keeping the state on the physical\nfolio also avoids depending on a virtual address that may change before a\nfault occurs.\n\nv2:\n- Replace the retired-PFN XArray with an embedded bitmap. (Matthew Brost)\n- Mark every base page covered by a migrated folio so retirement remains\n  valid if the folio is later split.\n\nv3:\n- Store the migrated state in a low bit of zone_device_data instead of\n  adding virtual-range and bitmap tracking to the ZDD. (Matthew Brost)\n- Mask the flag when retrieving the ZDD and preserve it when splitting\n  a folio.\n- Drop the pre-existing fixes already covered by Matthew Brost\u0027s series:\n  https://patchwork.freedesktop.org/series/171651/\n\nv4:\n- Advance by the folio size only for migration entries marked with\n  MIGRATE_PFN_COMPOUND. (Sashiko)\n\nv5:\n- Simplify ZDD flag updates and folio iteration. (Matthew Brost)\n- Skip retired device-private folios in the CPU-fault path. (Matthew Brost)\n- Preserve flag bits while taking a new ZDD reference for split folios.\n\nv6:\n- Restore MIGRATE_PFN_COMPOUND-aware stepping so non-compound migration\n  entries are processed one at a time.
