CVE-2026-64499
Description
A flaw was found in the Linux kernel's ti-ads1119 Analog-to-Digital Converter (ADC) driver. This vulnerability occurs during the buffer pre-enable process, where a Power Management (PM) reference is not properly released if an I2C communication error occurs. This oversight can lead to a resource leak, potentially causing the affected device to remain active indefinitely and consume system resources, which could result in a denial of service.
