CVE-2024-50302: HID: core: zero-initialize the report buffer

Noroxi assessment

Priority: Plan (action score 52/100)

  • CISA has confirmed exploitation in the wild (Mar 4, 2025). Remediation deadline for US federal agencies: Mar 25, 2025.
  • Probability of exploitation in the next 30 days: 0.81% (FIRST EPSS); higher than 56.9% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 05ade5d4337867929e7ef664e7ac8e0c734f1aaf, 177f25d1292c7e16e1199b39c85480f7f8815552, 1884ab3d22536a5c14b17c78c2ce76d1734e8b0b; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 4, 2025. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 25, 2025.
