CVE-2022-3903 — An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel
Medium
CVSS 4.6
An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the resources, causing denial of service or potentially crashing the system.

Matched remediation archetype
Resource exhaustion and denial of service
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
- Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
- Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.
Remediate safely
- Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
- Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
- Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
