Revision 27de809a3d83a6199664479ebb19712533d6fd9b authored by Björn Töpel on 28 October 2021, 12:51:15 UTC, committed by Jakub Kicinski on 28 October 2021, 15:14:30 UTC
The bpf_jit_binary_free() function requires a non-NULL argument. When
the RISC-V BPF JIT fails to converge in NR_JIT_ITERATIONS steps,
jit_data->header will be NULL, which triggers a NULL
dereference. Avoid this by checking the argument, prior calling the
function.
