NVDhttps://nvd.nist.gov/vuln/detail/CVE-2023-52581
CWEhttps://cwe.mitre.org/data/definitions/401.html

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

netfilter: nf_tables: fix memleak when more than 255 elements expired

When more than 255 elements expired were supposed to switch to a new gc container structure.

This never happens: u8 type will wrap before reaching the boundary and nft_trans_gc_space() always returns true.

This means we recycle the initial gc container structure and lose track of the elements that came before.

While at it, dont deref gc after weve passed it to call_rcu.

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.
