A vulnerability was found in Linux Kernel. It has been declared as problematic. This vulnerability affects the function vsock_connect of the file net/vmw_vsock/af_vsock.c. The manipulation leads to memory leak. The complexity of an attack is rather high. The exploitation appears to be difficult. It is recommended to apply a patch to fix this issue. VDB-211930 is the identifier assigned to this vulnerability.

Weakness

The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.

Potential Mitigations

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
  • For example, glibc in Linux provides protection against free of invalid pointers.
  • When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
  • To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
