In the Linux kernel, the following vulnerability has been resolved: hwmon: (nct6775-core) Fix number of temperature registers for NCT6116 Unlike NCT6106, NCT6116 only has three temperature registers, and with it only three temperature source and temperature source configuration registers. The register addresses match those of NCT6106 and can be re-used. The code used a separate array to list the temperature source registers for NCT6116, but used the size of the NCT6106 register array to set the number of registers. The NCT6106 register array provides six addresses, while the temperature source register array for NCT6116 only provides three addresses. This causes a KASAN report. BUG: KASAN: global-out-of-bounds in nct6775_probe+0x936/0x46f0 [nct6775] Read of size 2 at addr ffffffffc19561a6 by task modprobe/954 ...

Fix the problem by hard-coding the number of temperature and temperature configuration registers to three for NCT6116. Drop the unnecessary NCT6116_REG_TEMP_SOURCE array and re-use NCT6106_REG_TEMP_SOURCE.
