CVE-2026-98218 Details

Description

In the Linux kernel, the following vulnerability has been resolved: i2c: atr: fix dangling adapter pointer on add failure i2c_atr_add_adapter() stores atr->adapter[chan_id] before i2c_add_adapter() so that the I2C bus notifier can match child clients during registration. On failure the channel is freed but the slot was left pointing at freed memory, which can lead to use-after-free in i2c_atr_del_adapter() / cleanup and also block reuse with -EEXIST. Clear the slot on the i2c_add_adapter() error path before freeing chan.
