Buffer overflow in the perf_copy_attr function in kernel/perf_counter.c in the Linux kernel 2.6.31-rc1 allows local users to cause a denial of service (crash) and execute arbitrary code via a "big size data" to the perf_counter_open system call.

Does this matter?
Lower severity and a low EPSS score (1.80%). Track it; it rarely justifies an emergency change on its own.
