Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 0b0ca135-0b70-47e7-9f44-1890c2a1c46c | ||||
| CVSS 3.1 | MEDIUM | [email protected] |
Solution
Limit AEAD Associated Data length to prevent overflows.
- Update the Linux kernel to the resolved version.
- Apply the specific crypto patch for af_alg.
- Ensure associated data lengths do not exceed the cap.
