CVE-2026-90386

This Linux kernel vulnerability affects the DesignWare I3C master driver (drivers/i3c/master/dw-i3c-master.c:905). On an empty I3C bus, the ENTDAA (Enhanced Dynamic Address Assignment) command assigns no devices, causing cmd->rx_len to equal master->maxdevs. The resulting GENMASK() index be...
