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.
Conclusion & alert: CVE-2026-46001 is rated Low Risk (4.9/100): low exploitation likelihood (EPSS 0.02%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
