This affects the function DecodePlainMmMessage in the library src/lib/nas/encode.cpp of the component nr-gnb. Executing a manipulation can lead to uncaught exception. The attack can be launched remotely. The exploit has been published and may be used. This patch is called 1ae9bf2062b57595dbcbc4bc1d0a0ccf06815bac. It is best practice to apply a patch to resolve this issue.

GHSA-MGJ2-JQJQ-Q8GG
Vulnerability from github – Published: 2026-09-17 15:32 – Updated: 2026-10-05 22:45Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-gjq8-xm47-88rc. This link is maintained to preserve external references.
Original Description
vm2 is a sandbox library for running untrusted JavaScript in Node.js. In versions >= 3.10.0 and <= 3.11.7, Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary; only Promises created inside the sandbox are wrapped with a rejection-swallowing handler (lib/setup-sandbox.js), and the bridge only installs host-side rejection sanitizers when sandbox code calls .then/.catch/.finally. As a result, code running in the sandbox can invoke a host function that returns a rejected Promise (for example events.once() exposed via the NodeVM events builtin, or any embedder-provided Promise-returning API) and simply ignore the return value, leaving the host Promise unhandled so that Node.js's default unhandled-rejection behavior terminates the host process. This is an incomplete fix of GHSA-hw58-p9xv-2mjh. The issue is fixed in version 3.11.8.

GHSA-MJW4-JJ88-V687
Vulnerability from github – Published: 2024-07-09 14:13 – Updated: 2024-11-18 16:26Impact
The phonenumber parsing code may panic due to a reachable assert! guard on the phonenumber string.
In a typical deployment of rust-phonenumber, this may get triggered by feeding a maliciously crafted phonenumber, e.g. over the network, specifically strings of the form +dwPAA;phone-context=AA, where the "number" part potentially parses as a number larger than 2^56.
Since f69abee1/0.3.4/#52.
0.2.x series is not affected.
Patches
Upgrade to 0.3.6 or higher.
Workarounds

References
Whereas https://github.com/whisperfish/rust-phonenumber/issues/69 did not provide an example code path, property testing found a few: +dwPAA;phone-context=AA.

GHSA-MW3Q-R9WH-H2FF
Vulnerability from github – Published: 2026-05-21 19:50 – Updated: 2026-06-10 13:41Impact
A remote, unauthenticated denial-of-service vulnerability in MerkleRadixTrie::put_chunk allows any state-sync peer to crash any node performing state synchronization (freshly joining nodes and recovering nodes).
A malicious peer can respond to a RequestChunk with a ResponseChunk::Chunk whose first TrieItem.key is the empty (ROOT) key. The chunk passes sorting, range, and Merkle-proof validation, but when put_raw tries to store a value at the root node, it calls TrieNode::put_value(...).unwrap(), which returns Err(RootCantHaveValue) and panics, aborting the node process. The panic fires on the first malicious chunk the victim commits; no rate limit or authentication gate caps the attack.
Impacted: any node running state sync against untrusted peers — this includes fresh nodes performing initial download and existing nodes recovering from data loss. Honest nodes never construct ROOT-keyed items, so non-syncing operation is unaffected.
Patches
See PR.
Workarounds
There is no safe in-process workaround: any peer serving state-sync data can trigger the crash and the code path is not guarded by a feature flag.

"details": "### Impact\n\nA remote, unauthenticated denial-of-service vulnerability in `MerkleRadixTrie::put_chunk` allows any state-sync peer to crash any node performing state synchronization (freshly joining nodes and recovering nodes).\n\nA malicious peer can respond to a `RequestChunk` with a `ResponseChunk::Chunk` whose first `TrieItem.key` is the empty (ROOT) key. The chunk passes sorting, range, and Merkle-proof validation, but when `put_raw` tries to store a value at the root node, it calls `TrieNode::put_value(...).unwrap()`, which returns `Err(RootCantHaveValue)` and panics, aborting the node process. The panic fires on the first malicious chunk the victim commits; no rate limit or authentication gate caps the attack.\n\nImpacted: any node running state sync against untrusted peers \u2014 this includes fresh nodes performing initial download and existing nodes recovering from data loss. Honest nodes never construct ROOT-keyed items, so non-syncing operation is unaffected.\n\n### Patches\n\nSee [PR](https://github.com/nimiq/core-rs-albatross/pull/3762).\n\n### Workarounds\n\nThere is no safe in-process workaround: any peer serving state-sync data can trigger the crash and the code path is not guarded by a feature flag.\n\n### Resources\n\n- Fix commit: (link to the merged PR commit, once merged)\n- Affected code: [`primitives/trie/src/trie.rs`](https://github.com/nimiq/core-rs-albatross/blob/albatross/primitives/trie/src/trie.rs) \u2014 `put_chunk` (around line 819) and `put_raw` (around line 351)",

GHSA-P25M-JPJ4-QCRR
Vulnerability from github – Published: 2023-09-13 18:31 – Updated: 2026-01-12 19:17Lack of error handling in the TCP server in Google's gRPC starting version 1.23 on posix-compatible platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number of connections with the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC Java, and Go are NOT affected.
