Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.18.0-rc5-arm64-renesas-00116-g73636105874d-dirty #166
Description
A vulnerability has been resolved in the Linux kernel. The issue is related to the gpio-keys module, which can either accept gpios or interrupts. The module initializes delayed work in case of gpios only and is only used if the debounce timer is not used. The vulnerability occurs when the gpio keys module is unloaded and an interrupt pin is used instead of GPIO, causing a warning and a call trace.
Recommendations
For Linux kernel versions prior to 5.18.0-rc5-arm64-renesas-00116-g73636105874d-dirty #166, update to a newer version that includes the fix for this issue. As a temporary workaround, consider disabling the gpio keys module when using interrupt pins instead of GPIO to minimize the risk of exploitation.
