Description

This security bulletin contains information about 1 vulnerability.


1) Use of Out-of-range Pointer Offset (CVE-ID: CVE-2026-53356)

CWE-ID: CWE-823 - Use of Out-of-range Pointer Offset

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to disclose or modify unintended memory contents.

The vulnerability exists due to improper pointer handling in i915_gem_object_pread_phys and i915_gem_object_pwrite_phys in the i915 GEM physical buffer object handling code when processing pread or pwrite operations with a non-zero offset. A local user can supply crafted offset values to access the wrong parts of a physical buffer object to disclose or modify unintended memory contents.

The issue affects physical buffer objects on impacted platforms using overlay or cursor planes with physical mapping.
