DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

i2c: core: fix adapter deregistration race

Adapters can be looked up by their id using i2c_get_adapter() which takes a reference to the embedded struct device.

Remove the adapter from the IDR before tearing it down during deregistration (and on registration failure) to make sure its resources are not accessed after having been freed (e.g. the device name).

AnalysisAI

Local privilege escalation in the Linux kernel's I2C subsystem allows a low-privileged local attacker to compromise system integrity, confidentiality, and availability via a race condition during I2C adapter deregistration. The vulnerability affects kernel versions from 2.6.31 up to unpatched releases, with fixes available in stable trees 5.15.212, 6.1.178, 6.6.145, 6.12.96, 6.18.39, 7.1.4, and 7.2-rc1. No public exploit code or active exploitation is currently reported, and EPSS indicates a low exploitation probability (0.21%).
