Subject: There is a potential buffer overflow issue in bmi323
Date: Thu, 12 Sep 2024 17:50:12 +0800 [thread overview]
Message-ID: <ZuK5VH179B4j0jjm@thinkpad.> (raw)
Hi,
I reviewed the following code in drivers/iio/imu/bmi323/bmi323_core.c:
2245 for (unsigned int i = 0; i < ARRAY_SIZE(bmi323_ext_reg_savestate); i++) { <-
2246 ret = bmi323_write_ext_reg(data, bmi323_reg_savestate[i], <-
2247 savestate->reg_settings[i]);
2248 if (ret) {
2249 dev_err(data->dev,
2250 "Error writing bmi323 external reg 0x%x: %d\n",
2251 bmi323_reg_savestate[i], ret);
2252 return ret;
2253 }
2254 }
The array size of the "bmi323_ext_reg_savestate" is twelve, and the
array size of "bmi323_reg_savestate" is nine.
Is it possible that "bmi323_reg_savestate" may have buffer overflow
issue?
