Linux kernel gfs2 denial of service
| kernel-gfs2-dos (30307) |  Medium Risk |
Description:
The Linux kernel is vulnerable to a denial of service caused by a NULL pointer dereference in the init_journal function in the gfs2 filesystem code. A local attacker could mount a specially-crafted stream to cause the system to crash.
*CVSS:
| Base Score: | 3.5 |
| Access Vector: | Local |
| Access Complexity: | Low |
| Authentication: | Not Required |
| Confidentiality Impact: | None |
| Integrity Impact: | None |
| Availability Impact: | Complete |
| Temporal Score: | 2.7 |
| Exploitability: | Proof-Of-Concept |
| Remediation Level: | Official-Fix |
| Report Confidence: | Confirmed |
Consequences:
Denial of Service
Remedy:
For Ubuntu Linux:
