CVE-2026-53356 is a Linux kernel vulnerability in the drm/i915/gem subsystem affecting physical buffer object pread and pwrite operations when a non-zero offset is supplied. The flaw arises because sg_page() returns a struct page pointer rather than a void pointer, leading to incorrect pointer scaling in the phys BO access path. As a result, reads and writes are performed against the wrong portions of the buffer object instead of the intended offset. The issue was noted as affecting legacy i915 platform usage involving overlay or cursor planes with physical mapping, with Gen3/945G/Lakeport identified as the last impacted platform class.
