CVE-2021-38160 (GCVE-0-2021-38160)
Vulnerability from cvelistv5 – Published: 2021-08-07 03:31 – Updated: 2024-08-04 01:37 Disputed
VLAI
EPSS
Summary
In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior
Severity
No CVSS data available.
