Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2026-43368)

CWE-ID: CWE-190 - Integer overflow

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


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to an integer overflow in the i915 GEM shmem scatterlist handling when populating a scatterlist table with folio-backed pages for a GEM shmem object of size 4 gb or more. A local user can trigger a page fault on a specially crafted large object to cause a denial of service.

The issue can occur if the total byte length recorded in a single scatterlist reaches or crosses the 4 gb limit, leading to an unexpected premature end of the object's backing pages.
