LoongArch: BPF: Fix jump offset calculation in tailcall

...

CVE-2025-38723

CVE-2025-38723 concerns the Linux kernel, specifically LoongArch BPF tailcall handling. The issue arises in the tailcall jump offset calculation when bpf_int_jit_compile() fails to initialize the JIT context, leaving out_offset = -1. Consequently, the computed jmp_offset = (out_offset - cur_offse...
