Description
A flaw was found in the Linux kernel's Arm Ethos-U accelerator driver. A local user can submit a job configured with a zero Static Random-Access Memory (SRAM) size while still performing SRAM operations in the command stream. Because the driver skips setting the region base register when the size is zero, it reuses a stale base address from a previous job. This issue can allow an attacker to access memory associated with prior jobs, leading to information disclosure or data corruption.
