RUSTSEC-2025-0126
No affected components available
A heap-buffer-overflow vulnerability exists in the Rust wrapper for libnftnl, triggered via the nftnl::Batch::with_page_size constructor. When a small or malformed page size is provided, the underlying C code allocates an insufficient buffer, leading to out-of-bounds writes during batch initialization.
The flaw was fixed in commit 94a286f by adding an overflow check:
batch_page_size
.checked_add(crate::nft_nlmsg_maxsize())
.expect("batch_page_size is too large and would overflow");
Mitigation
