Event History
Frequently Asked Questions
Which systems should be reviewed for exposure?
Review systems running the Linux kernel that include the Input soc_button_array component. The available data does not identify affected kernel versions or configurations.
What condition is addressed by the fix?
The fix prevents access to the first package element when the associated package count is zero. This indicates the issue is tied to handling an empty button-description package.
What prioritization information is available?
The reported risk is 20, and the EPSS value is 0.00184 (p7). No exploit prerequisites, attack vector, or workaround are provided in the available data.
