In the Linux kernel, the following vulnerability has been resolved:
riscv, 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.
Fix this by adding the missing kfree(jit_data->ctx.offset) in
bpf_jit_free().
