CVE-2026-64524

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/hyperv: validate resolution_count and fix WIN8 fallback<br /> <br /> A SYNTHVID_RESOLUTION_RESPONSE with resolution_count &gt; 64 walks past<br /> the supported_resolution[SYNTHVID_MAX_RESOLUTION_COUNT] array in the<br /> parse loop. Bound resolution_count against the array size, folded<br /> into the existing zero-check.<br /> <br /> When the WIN10 resolution probe fails, the caller in<br /> hyperv_connect_vsp() left hv-&gt;screen_*_max / preferred_* unpopulated,<br /> which sets mode_config.max_width / max_height to 0 and makes<br /> drm_internal_framebuffer_create() reject every userspace framebuffer<br /> with -EINVAL. The pre-WIN10 branch had the same gap for<br /> preferred_width / preferred_height. Use a single post-probe fallback<br /> guarded by screen_width_max == 0 so both paths converge on the WIN8<br /> defaults.
