CVE-2025-40151

Estado: AplazadaAlta (7.8)—

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

LoongArch: BPF: No support of struct argument in trampoline programs

The current implementation does not support struct argument. This causes a oops when running bpf selftest:

Reject it for now.
