CWEhttps://cwe.mitre.org/data/definitions/404.html

The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.

Weakness

The product does not release or incorrectly releases a resource before it is made available for re-use.

Affected Software

Name Vendor Start Version End Version
Linux_kernel Linux * 4.10.3 (including)

Potential Mitigations

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
