Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A user-after-free vulnerability exists in the Linux kernel related to HID (Human Interface Device) processing, specifically within the handling of ASUS ROG N-Key keyboards. A maliciously crafted HID descriptor, utilizing the
HID UP UNDEFINED Usage Page, can trigger the vulnerability. This occurs because capability bitmaps may not be properly set during usage configuration, leading to the freeing of an input device and subsequent use of the freed memory when the device name is written. This can lead to a system crash as demonstrated by a KASAN (Kernel Address Sanitizer) splat.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
