Description
A flaw was found in the Linux kernel's Arm Ethos-U accelerator driver. When the mapping of Static Random-Access Memory (SRAM) fails during device initialization, the driver fails to reset the memory size to zero. Consequently, a local user can submit processing jobs that access physical address zero, leading to unauthorized memory access, data corruption, or a Denial of Service (DoS).
