      "title": "hwmon: (nct6775-core) Fix number of temperature registers for NCT6116",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (nct6775-core) Fix number of temperature registers for NCT6116\n\nUnlike NCT6106, NCT6116 only has three temperature registers, and with\nit only three temperature source and temperature source configuration\nregisters. The register addresses match those of NCT6106 and can be\nre-used.\n\nThe code used a separate array to list the temperature source registers\nfor NCT6116, but used the size of the NCT6106 register array to set\nthe number of registers. The NCT6106 register array provides six addresses,\nwhile the temperature source register array for NCT6116 only provides three\naddresses. This causes a KASAN report.\n\nBUG: KASAN: global-out-of-bounds in nct6775_probe+0x936/0x46f0 [nct6775]\nRead of size 2 at addr ffffffffc19561a6 by task modprobe/954\n...\nCall Trace:\n dump_stack+0x7d/0xa7\n print_address_description.constprop.0+0x1c/0x220\n ? __kasan_kmalloc.constprop.0+0xc9/0xd0\n ? __kmalloc_node_track_caller+0x194/0x5b0\n ? nct6775_probe+0x936/0x46f0 [nct6775]\n ? nct6775_probe+0x936/0x46f0 [nct6775]\n...\n\nFix the problem by hard-coding the number of temperature and temperature\nconfiguration registers to three for NCT6116. Drop the unnecessary\nNCT6116_REG_TEMP_SOURCE array and re-use NCT6106_REG_TEMP_SOURCE.",
