CVE-2026-64149

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...

CVE-2026-64149

The Linux kernel's dma_map_resource() used pfn_valid() to verify a PFN range is not RAM, but this check only confirms memory map availability, not actual RAM backing. On ARM64 SPARSEMEM systems with 128MB sections, MMIO addresses sharing a section with RAM falsely triggered WARN_ON_ONCE, causing ...

CVE-2026-64149 dma-mapping: move dma_map_resource() sanity check into debug code

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...

CVE-2023-53545

CVE-2023-53545 affects the Linux kernel DRM/AMDGPU path. The issue arises when unmapping/removing csa_va during VM operations: the Root PD BO must be reserved before unmapping a bo_va to prevent lockdep warnings. The v2 fix changes the NULL-check from amdgpu_mcbp to fpriv->csa_va. Consequence ...
