CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2026-45971
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).
