Description

In the Linux kernel, the following vulnerability has been resolved: HID: magicmouse: Do not crash on missing msc->input Fake USB devices can send their own report descriptors for which the input_mapping() hook does not get called. In this case, msc->input stays NULL, leading to a crash at a later time. Detect this condition in the input_configured() hook and reject the device. This is not supposed to happen with actual magic mouse devices, but can be provoked by imposing as a magic mouse USB device.

• linux linux kernel (>= 2.6.37 < 5.10.252) • linux linux kernel (>= 5.11 < 5.15.202) • linux linux kernel (>= 5.16 < 6.1.165) • linux linux kernel (>= 6.2 < 6.6.128) • linux linux kernel (>= 6.7 < 6.12.75) • linux linux kernel (>= 6.13 < 6.18.16) • linux linux kernel (>= 6.19 < 6.19.6)
