"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncpufreq: qcom: fix writes in read-only memory region\n\nThis commit fixes a kernel oops because of a write in some read-only memory:\n\n\t[ 9.068287] Unable to handle kernel write to read-only memory at virtual address ffff800009240ad8\n\t..snip..\n\t[ 9.138790] Internal error: Oops: 9600004f [#1] PREEMPT SMP\n\t..snip..\n\t[ 9.269161] Call trace:\n\t[ 9.276271] __memcpy+0x5c/0x230\n\t[ 9.278531] snprintf+0x58/0x80\n\t[ 9.282002] qcom_cpufreq_msm8939_name_version+0xb4/0x190\n\t[ 9.284869] qcom_cpufreq_probe+0xc8/0x39c\n\t..snip..\n\nThe following line defines a pointer that point to a char buffer stored\nin read-only memory:\n\n\tchar *pvs_name = \"speedXX-pvsXX-vXX\";\n\nThis pointer is meant to hold a template \"speedXX-pvsXX-vXX\" where the\nXX values get overridden by the qcom_cpufreq_krait_name_version function. Since\nthe template is actually stored in read-only memory, when the function\nexecutes the following call we get an oops:\n\n\tsnprintf(*pvs_name, sizeof(\"speedXX-pvsXX-vXX\"), \"speed%d-pvs%d-v%d\",\n\t\t speed, pvs, pvs_ver);\n\nTo fix this issue, we instead store the template name onto the stack by\nusing the following syntax:\n\n\tchar pvs_name_buffer[] = \"speedXX-pvsXX-vXX\";\n\nBecause the `pvs_name` needs to be able to be assigned to NULL, the\ntemplate buffer is stored in the pvs_name_buffer and not under the\npvs_name variable."
