CVE-2022-23486 — libp2p-rust denial of service vulnerability from lack of resource management

2026-10-14T21:45:35.961168+00:00

Affected: libp2p rust-libp2p

libp2p-rust is the official rust language Implementation of the libp2p networking stack. In versions prior to 0.45.1 an attacker node can cause a victim node to allocate a large number of small memory chunks, which can ultimately lead to the victim’s process running out of memory and thus getting killed by its operating system. When executed continuously, this can lead to a denial of service attack, especially relevant on a larger scale when run against more than one node of a libp2p based network. Users are advised to upgrade to `libp2p` `v0.45.1` or above. Users unable to upgrade should reference the DoS Mitigation page for more information on how to incorporate mitigation strategies, monitor their application, and respond to attacks: https://docs.libp2p.io/reference/dos-mitigation/.

2026-10-14T21:45:35.961229+00:00

Affected: crates.io: libp2p

libp2p allows a potential attacker to cause victim p2p node to run out of memory

The out of memory failure can cause crashes where libp2p is intended to be used within large scale networks leading to potential Denial of Service (DoS) vector

Users should upgrade or reference the [DoS mitigation strategies](https://docs.libp2p.io/reference/dos-mitigation/).
