CVE-2026-64499: iio: adc: ti-ads1119: fix PM reference leak in buffer preenable

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 6537f08100189d12bec4975000244e6ac4873c28, adf4bc07f814da8329278d32600147f5a150938c, f40292fb19399a3c3f82de698023ba87c01e66cf.

Low priority for now. Upgrade to Linux Linux 6537f08100189d12bec4975000244e6ac4873c28, adf4bc07f814da8329278d32600147f5a150938c, f40292fb19399a3c3f82de698023ba87c01e66cf or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
