Lifecycle Timeline
1DescriptionNVD
An issue was discovered in the Linux kernel before 4.8. Incorrect access checking in overlayfs mounts could be used by local attackers to modify or truncate files in the underlying filesystem.
AnalysisAI
An issue was discovered in the Linux kernel before 4.8. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. This Incorrect Authorization vulnerability could allow attackers to bypass authorization checks to access restricted resources.
Technical ContextAI
This vulnerability is classified as Incorrect Authorization (CWE-863), which allows attackers to bypass authorization checks to access restricted resources. An issue was discovered in the Linux kernel before 4.8. Incorrect access checking in overlayfs mounts could be used by local attackers to modify or truncate files in the underlying filesystem. Affected products include: Linux Linux Kernel, Netapp Active Iq Performance Analytics Services, Netapp Element Software, Opensuse Leap. Version information: before 4.8..
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Review and test authorization logic, implement consistent access control checks, use centralized authorization framework.
