In the Linux kernel, the following vulnerability has been resolved: bpf: Disable preemption in bpf_get_stackid The get_perf_callchain call needs disabled preemption plus we need it disabled as long as we access its returned trace entries buffer. Note the bpf_get_stackid_pe function is executed already with preemption disabled.
