CVE-2024-50302 is a privilege escalation vulnerability found in the HID (Human Interface Device) USB component of the Linux kernel. Exploitation is achieved through specially crafted HID reports, which can cause a leak of uninitialized kernel memory to a local attacker. This vulnerability has been reportedly used in targeted attacks. This flaw allows unauthorized access to sensitive kernel memory, potentially enabling further malicious actions on the affected device. It was patched by Google in March 2025 and has been added to CISA's Known Exploited Vulnerabilities Catalog due to evidence of active exploitation.

Description: 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.
