Linux Kernel ptrace denial of service
| linux-kernel-ptrace-dos (41501) |
Description:
Linux Kernel is vulnerable to a denial of service, caused by an error in ptrace. A local attacker could exploit this vulnerability using the user-area-padding test to cause a kernel panic.
*CVSS:
| Base Score: | 2.1 |
| Access Vector: | Local |
| Access Complexity: | Low |
| Authentication: | None |
| Confidentiality Impact: | None |
| Integrity Impact: | None |
| Availability Impact: | Partial |
| Temporal Score: | 1.6 |
| Exploitability: | Unproven |
| Remediation Level: | Official-Fix |
| Report Confidence: | Confirmed |
Consequences:
Denial of Service
