CVE-2026-53356

HighCVSS 7.8/10Last modified Oct 19, 2026

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)
