"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncpufreq: intel_pstate: Fix crash during turbo disable\n\nWhen the system is booted with kernel command line argument \"nosmt\" or\n\"maxcpus\" to limit the number of CPUs, disabling turbo via:\n\n echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo\n\nresults in a crash:\n\n PF: supervisor read access in kernel mode\n PF: error_code(0x0000) - not-present page\n PGD 0 P4D 0\n Oops: Oops: 0000 [#1] SMP PTI\n ...\n RIP: 0010:store_no_turbo+0x100/0x1f0\n ...\n\nThis occurs because for_each_possible_cpu() returns CPUs even if they\nare not online. For those CPUs, all_cpu_data[] will be NULL. Since\ncommit 973207ae3d7c (\"cpufreq: intel_pstate: Rearrange max frequency\nupdates handling code\"), all_cpu_data[] is dereferenced even for CPUs\nwhich are not online, causing the NULL pointer dereference.\n\nTo fix that, pass CPU number to intel_pstate_update_max_freq() and use\nall_cpu_data[] for those CPUs for which there is a valid cpufreq policy."
