CVE-2024-50302 revealed a vulnerability in the Linux kernel’s HID (Human Interface Device) core, where uninitialized buffers could leak kernel memory.
When HID reports were processed, the kernel failed to zero-initialize allocated buffers, allowing specially crafted HID reports to read sensitive kernel memory containing cryptographic keys or other confidential data.
The vulnerability required physical access to attach malicious USB devices but demonstrated the risks inherent in trusting external hardware.
System administrators should consider blocking untrusted USB devices if kernel updates cannot be applied immediately.
