In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fix memory leak in bpf_jit_free() When bpf_int_jit_compile() is called for subprograms, it returns early during the first pass (!prog->is_func || extra_pass is false), keeping ctx->offset alive for the subsequent extra pass. If JIT compilation fails for a later subprogram, the BPF core aborts and calls bpf_jit_free() to clean up the first subprogram. However, bpf_jit_free() fails to free jit_data->ctx.offset, which causes a memory leak of the JIT context offsets array. So fix this by adding the missing kvfree(jit_data->ctx.offset) in bpf_jit_free().
