CVE-2024-50302: HID: core: zero-initialize the report buffer
First published: Tue Nov 19 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report.
