CVE-2026-31767

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/i915/dsi: Don&amp;#39;t do DSC horizontal timing adjustments in command mode<br /> <br /> Stop adjusting the horizontal timing values based on the<br /> compression ratio in command mode. Bspec seems to be telling<br /> us to do this only in video mode, and this is also how the<br /> Windows driver does things.<br /> <br /> This should also fix a div-by-zero on some machines because<br /> the adjusted htotal ends up being so small that we end up with<br /> line_time_us==0 when trying to determine the vtotal value in<br /> command mode.<br /> <br /> Note that this doesn&amp;#39;t actually make the display on the<br /> Huawei Matebook E work, but at least the kernel no longer<br /> explodes when the driver loads.<br /> <br /> (cherry picked from commit 0b475e91ecc2313207196c6d7fd5c53e1a878525)
