CVE-2026-53356

Linux Linux, linux kernel

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)

Full remediation guide
  1. 1
    Identify

    Confirm that Linux Linux, linux kernel and an affected version are present.

  2. 2
    Prioritize

    Combine exploitation signals with asset exposure and business criticality.

  3. 3
    Remediate

    Follow the vendor advisory or supported update path and preserve rollback options.

  4. 4
    Verify

    Recheck the version, service health, access paths, and relevant logs.
