CVE-2026-64499 (opens in a new tab)How to fix?
Upgrade Echo:latest linux-6.12 to version 6.12.100-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
