CVE-2026-53356 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix phys BO pread/pwrite with offset sg_page() returns struct page pointer not (void *) so the scaling of pread/pwrite is wrong for phys BO and wrong parts of BO would be accessed if non-zero offset is used. Last impacted platform with overlay or cursor planes using phys mapping was Gen3/945G/Lakeport. (cherry picked from commit 3e49a2f85070b2fb672c1e0fdba281a4ea3aebe6)
A vulnerability in the Linux kernel's handling of physically mapped buffer objects (BOs) in the Direct Rendering Manager (DRM) can lead to incorrect data access during read and write operations. This issue arises because the function that retrieves the scatterlist page pointer returns a struct page pointer instead of a void pointer, causing improper scaling of read/write operations. As a result, if a non-zero offset is used, incorrect parts of the buffer object may be accessed. This vulnerability affects the last platform with overlay or cursor planes using physical mapping, which was Gen3/945G/Lakeport.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is available in the Linux kernel stable tree.
