CVE-2026-53356 is an incorrect pointer-scaling vulnerability in the Linux kernel Intel i915 GEM component. Physical buffer-object pread and pwrite operations incorrectly apply offsets to the struct page pointer returned by sg_page(), rather than treating the offset as a byte displacement. A non-zero offset consequently accesses the wrong portions of the buffer object. The affected usage involves overlay or cursor planes using physical mapping; the last impacted platform identified is Intel Gen3/945G/Lakeport.
