CVE-2024-50302: Linux Kernel Use of Uninitialized Resource Vulnerability
Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.
Generated by VEDAS. Scores as of 2026-11-01 19:19 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.
What it is
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.
Description quoted from the CVE record (assigned by Linux, published 2024-11-19).
Weakness: CWE-908 Use of Uninitialized Resource
How it can be exploited
Exploitable with local access with low attack complexity needing low privileges and no user interaction. Impact: confidentiality high, integrity none, availability none. CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
CISA assessment (SSVC): CISA assesses exploitation as active. Automatable: no. Technical impact: partial.
