Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 7.0.10. This affects the function tegra_i2c_mutex_lock of the component I2c Tegra. The manipulation with an unknown input leads to a locking vulnerability. CWE is classifying the issue as CWE-667. The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: fix pm_runtime leak on mutex_lock failure If tegra_i2c_mutex_lock() fails, the function returns without calling pm_runtime_put(), leaking the runtime PM reference acquired by the preceding pm_runtime_get_sync(). This prevents the device from ever entering runtime suspend. Add the missing pm_runtime_put() before returning on lock failure.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-64171 since 07/19/2026. The exploitability is told to be easy. An attack has to be approached locally.
