**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A kernel panic can occur when accessing DAT data due to the `i3c master bus init` function attaching I2C devices before I3C bus initialization. The DAT `alloc entry` is used before the DAT `init`, and if `i3c master bus init` fails, the DAT `cleanup` executes before device detachment, leading to the DAT `free entry` function being called. This scenario causes the driver to use DAT data when it is NULL. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
