CVE-2024-50302 (GCVE-0-2024-50302)
Vulnerability from cvelistv5 – Published: 2024-11-19 01:30 – Updated: 2026-05-23 15:55Title
HID: core: zero-initialize the report buffer
Summary
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.
