CVE-2024-40970

The CVE-2024-40970 issue affects the Linux kernel’s dw-axi-dmac component. It describes a hw_desc array overrun when many descriptors are chained (e.g., nr_buffers=3 with 3 segments per descriptor, leading to 9 hw_descs). Root cause is improper handling in axi_desc_put() relative to allocated hw_...
