5.5 · MEDIUMOverview
CVE-2022-49430 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
Input: gpio-keys - cancel delayed work only in case of GPIO
gpio_keys module can either accept gpios or interrupts. The module
initializes delayed work in case of gpios only and is only used if
debounce timer is not used, so make sure cancel_delayed_work_sync()
is called only when its gpio-backed and debounce_use_hrtimer is false.
This fixes the issue seen below when the gpio_keys module is unloaded and
an interrupt pin is used instead of GPIO:
