In the Linux kernel, the following vulnerability has been resolved: hwmon: (pt5161l) Fix bugs in pt5161l_read_block_data() Fix two bugs in pt5161l_read_block_data(): 1. Buffer overrun: The local buffer rbuf is declared as u8 rbuf[24], but i2c_smbus_read_block_data() can return up to I2C_SMBUS_BLOCK_MAX (32) bytes. The i2c-core copies the data into the caller's buffer before the return value can be checked, so the post-read length v
