  3. CVE-2023-53656
In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: Don't migrate perf to the CPU going to teardown The driver needs to migrate the perf context if the current using CPU going to teardown. By the time calling the cpuhp::teardown() callback the cpu_online_mask() hasn't updated yet and still includes the CPU going to teardown. In current driver's implementation we may migrate the context to the teardown CPU and leads to the below calltrace: ...
