  "description": "In the Linux kernel, the following vulnerability has been resolved:  cpufreq: intel_pstate: Fix crash during turbo disable  When the system is booted with kernel command line argument \u0022nosmt\u0022 or \u0022maxcpus\u0022 to limit the number of CPUs, disabling turbo via:   echo 1 \u003E /sys/devices/system/cpu/intel_pstate/no_turbo  results in a crash:   PF: supervisor read access in kernel mode  PF: error_code(0x0000) - not-present page  PGD 0 P4D 0  Oops: Oops: 0000 [#1] SMP PTI  ...  RIP: 0010:store_no_turbo\u002B0x100/0x1f0  ...  This occurs because for_each_possible_cpu() returns CPUs even if they are not online. For those CPUs, all_cpu_data[] will be NULL. Since commit 973207ae3d7c (\u0022cpufreq: intel_pstate: Rearrange max frequency updates handling code\u0022), all_cpu_data[] is dereferenced even for CPUs which are not online, causing the NULL pointer dereference.  To fix that, pass CPU number to intel_pstate_update_max_freq() and use all_cpu_data[] for those CPUs for which there is a valid cpufreq policy.",
