Answer in brief
CVE-2026-64499 records a Unknown severity vulnerability in iio: adc: ti-ads1119: fix PM reference leak in buffer preenable. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-ads1119: fix PM reference leak in buffer preenable ads1119_triggered_buffer_preenable() resumes the device with pm_runtime_resume_and_get() before starting a conversion. If i2c_smbus_write_byte() fails, the function returns the error directly and leaves the runtime PM usage counter elevated. The matching postdisable callback is not called when preenable fails, so the reference is leaked and the device may remain runtime-active indefinitely. Store the I2C transfer result in ret and drop the runtime PM reference on failure before returning the error.
