  "details": "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 validation does not prevent a stack overrun    if a device returns more than 24 bytes. Resize the buffer to    I2C_SMBUS_BLOCK_MAX.  2. Unexpected positive return on length mismatch: When all three    retries are exhausted because the device returns data with an    unexpected length, i2c_smbus_read_block_data() returns a positive    byte count. The function returns this directly, and callers treat    any non-negative return as success, processing stale or incomplete    buffer contents. Return -EIO when retries are exhausted with a    positive return value, preserving the negative error code on I2C    failure.",
