Description

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).

Affected configurations

• linux linux kernel (>= 4.20 < 5.4.125) • linux linux kernel (>= 5.5 < 5.10.43) • linux linux kernel (>= 5.11 < 5.12.10) • linux linux kernel 5.13
