CVE-2026-90035

A flaw was found in the drm/amd/display component of the Linux kernel. A local attacker, by connecting a specially crafted USB4/DPIA tunneling device, could trigger a division-by-zero error within the getestimatedbw function. This occurs when the device reports an estimated-bandwidth change befor...
