CVE-2026-43368

A flaw was found in the Linux kernel's graphics memory management (drm/i915) component. This vulnerability occurs when a large shared memory object's internal list of memory segments, called a scatterlist, is populated. If the total size of these segments exceeds 4 Gigabytes (GB), a numerical overflow can happen in the length calculation. This issue can cause applications using the affected memory to encounter unexpected errors, potentially leading to system instability or a denial of service.
