Ubuntu.comUB:CVE-2021-47120CVE-2021-47120
In the Linux kernel, the following vulnerability has been resolved: HID:
magicmouse: fix NULL-deref on disconnect Commit 9d7b18668956 (“HID:
magicmouse: add support for Apple Magic Trackpad 2”) added a sanity check
for an Apple trackpad but returned success instead of -ENODEV when the
check failed. This means that the remove callback will dereference the
never-initialised driver data pointer when the driver is later unbound
(e.g. on USB disconnect).
