Details

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: DR, Fix slab-out-of-bounds in mlx5cmddrcreatefte

When adding a rule with 32 destinations, we hit the following out-of-band access issue:

BUG: KASAN: slab-out-of-bounds in mlx5cmddrcreatefte+0x18ee/0x1e70

This patch fixes the issue by both increasing the allocated buffers to accommodate for the needed actions and by checking the number of actions to prevent this issue when a rule with too many actions is provided.
