по MITRE • 27.05.2026
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).
