RUSTSEC-2026-0045 Timing Side-Channel in AES-CCM Tag Verification in AWS-LC

Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis. The impacted implementations are through the EVP CIPHER API: EVPaes128ccm, EVPaes192ccm, and EVPaes256ccm. Customers of AWS servic...

RUSTSEC-2025-0127 CGGMP21 presignatures can be used in the way that significantly reduces security

This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously you could generate a presignature, and then choose a HD derivation path while issuing a partial signature via Presignature::setderivationpath,...

RUSTSEC-2025-0073 DoS vulnerability on `alloy_dyn_abi::TypedData` hashing

An uncaught panic triggered by malformed input to alloydynabi::TypedData could lead to a denial-of-service DoS via eip712signinghash. Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially...

RUSTSEC-2025-0070 Pingora MadeYouReset HTTP/2 vulnerability

Pingora deployments using versions prior to 0.6.0 that include HTTP/2 server support may be affected by the vulnerability described in CVE-2025-8671. Under certain conditions, Pingora applications may allocate buffers before the HTTP/2 reset and resulting stream cancellation is processed by the...

RUSTSEC-2025-0045 ConstStaticCell could have been used to pass non-Send values to another thread

ConstStaticCell could have been used to pass non-Send values to another thread, because T was not required to be Send while ConstStaticCell is Send. This was corrected by introducing a T: Send bound...

RUSTSEC-2025-0006 Hickory DNS failure to verify self-signed RRSIG for DNSKEYs

Summary The DNSSEC validation routines treat entire RRsets of DNSKEY records as trusted once they have established trust in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY with a public key that matches a configured trust anchor, all keys in that zone will be trusted to...

RUSTSEC-2024-0432 Malicious plugin names, recipients, or identities can cause arbitrary binary execution

A plugin name containing a path separator may allow an attacker to execute an arbitrary binary. Such a plugin name can be provided to the rage CLI through an attacker-controlled recipient or identity string, or an attacker-controlled plugin name via the -j flag. On UNIX systems, a directory...

RUSTSEC-2024-0428 Undefined behaviour in `kvm_ioctls::ioctls::vm::VmFd::create_device`

An issue was identified in the VmFd::createdevice function, leading to undefined behavior and miscompilations on rustc 1.82.0 and newer due to the function's violation of Rust's pointer safety rules. The function downcasted a mutable reference to its struct kvmcreatedevice argument to an immutabl...

RUSTSEC-2024-0373 `Endpoint::retry()` calls can lead to panicking

In 0.11.0, we overhauled the server-side Endpoint implementation to enable more careful handling of incoming connection attempts. However, some of the code paths that cleaned up state after connection attempts were processed confused the initial destination connection ID with the destination...

RUSTSEC-2023-0035 Adverserial use of `make_bitflags!` macro can cause undefined behavior

The macro relied on an expression of the form Enum::Variant always being a variant of the enum. However, it may also be an associated integer constant, in which case there's no guarantee that the value of said constant consists only of bits valid for this bitflag type. Thus, code like this could...

RUSTSEC-2021-0023 Incorrect check on buffer length when seeding RNGs

Summary: randcore::le::readu32into and readu64into have incorrect checks on the source buffer length, allowing the destination buffer to be under-filled. Implications: some downstream RNGs, including Hc128Rng but not the more widely used ChaChaRng, allow seeding using the SeedableRng::fromseed...

RUSTSEC-2020-0071 Potential segfault in the time crate

RUSTSEC-2026-0311 Stack overflow on deeply nested LaTeX input

The parser and layout engine in affected versions of latex-rust recurse once per level of nesting with no limit. Deeply nested input, such as \frac1…, braces, \sqrt…, \left, or superscripts nested hundreds or thousands of levels deep, exhausts the call stack. A stack overflow in Rust aborts the...

RUSTSEC-2026-0301 Double free in `StackVec::retain` when a predicate or element `Drop` panics

Summary StackVec::retain committed its new length to self.len only after its internal loop completed. If the retain predicate or a removed element's Drop implementation panicked before the loop finished, unwinding proceeded with self.len still equal to the original, pre-retain length, leaving...

RUSTSEC-2026-0272 Panic-safety unsoundness in `Stack::pop`, `Fifo::pop_front` and `Value::replace_stable` (use-after-free / double-free)

Three removal and replacement paths destroy an initialized value before committing the metadata change that removes it. Destruction runs T::drop, which is user code and may panic. If it does, the commit is skipped and the container still claims ownership of the already-destroyed value, so its own...

RUSTSEC-2026-0256 Panic-safety unsoundness in `truncate_back`, `truncate_front`, `clear`, and `extend_from_slice` (use-after-free / double-free)

Several methods in circular-buffer drop elements before updating the buffer's start/end metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the buffer still treats the already-dropped elements as live. When the buffer is later dropped or used after the panic ...

RUSTSEC-2026-0133 Invalid pointer arithmetic in `iter()` and `iter_mut()`

The iter and itermut APIs compute current = &children0 as const const RawAutoChild.sub1, which performs pointer subtraction going before the start of the allocation. This is undefined behavior per Rust's pointer arithmetic rules. This can be triggered through safe public APIs — iter and itermut —...

RUSTSEC-2026-0139 Null-pointer dereference and double-free via safe APIs

Two soundness violations exist in the Rust bindings for MetaCall: Null-pointer dereference: MetaCallFuture::newraw accepts a raw pointer without validation. The Debug impl calls Box::fromrawself.data on it. Passing a null pointer causes the Debug impl to construct a NonNull from null, producing...
