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_...

CVE-2024-40907

The CVE-2024-40907 issue is in the Linux kernel ionic driver XDP/TX path. A kernel panic occurs because ionic_rx_service frees the RX page after TX but does not reset the RX ring entry to NULL, causing a freed page to be reused. This is tied to the ionic_run_xdp() flow in ionic_txrx.c, leading to...
