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 | MEDIUM | [email protected] |
Solution
Fix memory leak by ensuring proper cleanup during error handling.
- Update the Linux kernel to include the fix.
- Ensure platform_get_irq() errors are handled correctly.
- Apply the goto label for proper resource cleanup.
