NVDhttps://nvd.nist.gov/vuln/detail/CVE-2023-53050
CWEhttps://cwe.mitre.org/data/definitions/401.html

In the Linux kernel, the following vulnerability has been resolved:

thunderbolt: Fix memory leak in margining

Memory for the usb4->margining needs to be relased for the upstream port of the router as well, even though the debugfs directory gets released with the router device removal. Fix this.

Weakness

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

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.
