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

bpf: Limit bpf program signature size

Practical BPF signatures are significantly smaller than KMALLOC_MAX_CACHE_SIZE

Allowing larger sizes opens the door for abuse by passing excessive size values and forcing the kernel into expensive allocation paths (via kmalloc_large or vmalloc).
