Read-only volume remount bypass via guest CAP_SYS_ADMIN

Affected versions of boxlite mount host directories shared via virtiofs as guest-side read-only by setting MSRDONLY from the guest. Because the default guest capability set included CAPSYSADMIN, untrusted code running inside a sandbox could execute mount -o remount,rw to re-flag the share as...

Unbounded 32-bit allocation

Both the SSH agent server and client accepted peer-controlled frame lengths without enforcing a maximum frame size. This could cause large memory allocations while parsing a maliciously crafted agent frame. A malicious peer could advertise an oversized frame length, causing the client or server t...

Potential undefined behavior when calling Remote::list()

When calling Remote::list for a remote of a git repository, when that remote does not advertise any references, git2 passes a null pointer to the unsafe function slice::fromrawparts. Based on the safety section documentation of function, data must be non-null even for slices of length zero. Thus,...

Name constraints for URI names were incorrectly accepted

Name constraints for URI names were ignored and therefore accepted. Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally. Since name constraints are restrictions on otherwis...

Panic in Standalone MAC Operations

An incorrect constant for the key length in libcrux-poly1305 caused the standalone MAC function libcruxpoly1305::mac to always panic with an out-of-bounds memory access. Impact Applications wishing to use libcrux-poly1305 as a standalone MAC would experience panics. The use of libcrux-poly1305 in...

`tracing-check` was removed from crates.io for malicious code

This is part of an ongoing campaign to attempt to typosquat crates in the polymarket-client-sdk ecosystem to exfiltrate user credentials. The malicious crate had 1 version published on 2026-02-24 approximately 4 hours before removal and had no evidence of actual downloads. There were no crates...

`polymarket-clients-sdk` was removed from crates.io for malicious code

It appeared to be typosquatting existing crate polymarket-client-sdk clients vs client and attempting to steal credentials from local files. The malicious crate had 6 versions published on 2026-02-05 and had been downloaded only 59 times. There were no crates depending on this crate on crates.io...

Incorrect X25519 clamping check rejects all secrets on import

Double Public Key Signing Function Oracle Attack on `ed25519-dalek`

Versions of ed25519-dalek prior to v2.0 model private and public keys as separate types which can be assembled into a Keypair, and also provide APIs for serializing and deserializing 64-byte private/public keypairs. Such APIs and serializations are inherently unsafe as the public key is one of th...

VecStorage Deserialize Allows Violation of Length Invariant

The Deserialize implementation for VecStorage did not maintain the invariant that the number of elements must equal nrows ncols. Deserialization of specially crafted inputs could allow memory access beyond allocation of the vector. This flaw was introduced in v0.11.0 086e6e due to the addition of...

project abandoned; migrate to the `aes-siv` crate

The Miscreant project has been abandoned and archived. The Rust implementation has been adapted into the new aes-siv crate which implements both the AES-CMAC-SIV and AES-PMAC-SIV constructions: Please migrate to the aes-siv crate. Alternatively see the aes-gcm-siv crate for a newer, faster...

split_at allows obtaining multiple mutable references to the same data

Affected versions of this crate assumed that Borrow was guaranteed to return the same value on .borrow. The borrowed index value was used to retrieve a mutable reference to a value. If the Borrow implementation returned a different index, the split arena would allow retrieving the index as a...

`Frame::copy_from_raw_parts` can lead to segfault without `unsafe`

fn Frame::copyfromrawparts is a safe API that can take a raw pointer and dereference it. It is possible to read arbitrary memory address with an arbitrarily fed pointer. This allows the safe API to access & read arbitrary address in memory. Feeding an invalid memory address pointer to the API may...

Unexpected panic when decoding tokens

Prior to 0.10.0 it was possible to have both decoding functions panic unexpectedly, by supplying tokens with an incorrect base62 encoding. The documentation stated that an error should have been reported instead...

Send bound needed on T (for Send impl of `Bucket2`)

Affected versions of this crate unconditionally implements Send for Bucket2. This allows sending non-Send types to other threads. This can lead to data races when non Send types like Cell or Rc are contained inside Bucket2 and sent across thread boundaries. The data races can potentially lead to...

Slock<T> allows sending non-Send types across thread boundaries

Slock unconditionally implements Send/Sync. Affected versions of this crate allows sending non-Send types to other threads, which can lead to data races and memory corruption due to the data race...

Generators can cause data races if non-Send types are used in their generator functions

The Generator type is an iterable which uses a generator function that yields values. In affected versions of the crate, the provided function yielding values had no Send bounds despite the Generator itself implementing Send. The generator function lacking a Send bound means that types that are...

ReaderResult should be bounded by Sync

Affected versions of this crate implements Sync for ReaderResult with the trait bound T: Send, E: Send. Since matching on the public enum ReaderResult provides access to &T & &E, allowing data race to a non-Sync type T or E. This can result in a memory corruption when multiple threads concurrentl...

beef::Cow lacks a Sync bound on its Send trait allowing for data races

Affected versions of this crate did not have a T: Sync bound in the Send impl for Cow. This allows users to create data races by making Cow contain types that are Send && !Sync like Cell or RefCell. Such data races can lead to memory corruption. The flaw was corrected in commit d1c7658 by adding...

array_queue pop_back() may cause a use-after-free

arrayqueue implements a circular queue that wraps around an array. However, it fails to properly index into the array in the popback function allowing the reading of previously dropped or uninitialized memory...

Allows viewing and modifying arbitrary structs as bytes

Affected versions of rgb crate allow viewing and modifying data of any type T wrapped in RGB as bytes, and do not correctly constrain RGB and other wrapper structures to the types for which it is safe to do so. Safety violation possible for a type wrapped in RGB and similar wrapper structures: If...

Flaw in generativity allows out-of-bounds access

Affected versions of this crate did not properly implement the generativity, because the invariant lifetimes were not necessarily dropped. This allows an attacker to mix up two arenas, using indices created from one arena with another one. This might lead to an out-of-bounds read or write access...

Uncontrolled recursion leads to abort in deserialization

Affected versions of this crate did not prevent deep recursion while deserializing data structures. This allows an attacker to make a YAML file with deeply nested structures that causes an abort while deserializing it. The flaw was corrected by checking the recursion depth. Note: clap 2.33 is not...

Possible double free during unwinding in SmallVec::insert_many

If an iterator passed to SmallVec::insertmany panicked in Iterator::next, destructors were run during unwinding while the vector was in an inconsistent state, possibly causing a double free a destructor running on two copies of the same value. This is fixed in smallvec 0.6.3 by ensuring that the...

Panic-safety unsoundness in `SplitVec::extend_from_slice` (uninitialized read)

SplitVec::extendfromslice increments the logical length self.len before cloning the incoming elements into the reserved slots. If an element's Clone panics mid-fill, unwinding leaves self.len counting slots that were never initialized. A later safe read get, indexing, iter then reads one of those...

Unbounded namespace-declaration allocation in `NsReader` enables memory-exhaustion denial of service

NsReader resolves namespaces by calling NamespaceResolver::push for every Start/Empty event before the event is returned to the caller. push iterated all xmlns / xmlns: attributes on the start tag and, for each one, appended the prefix bytes to an internal buffer and pushed a NamespaceBinding 32...

`exploration` was removed from crates.io for malicious code

A method within the exploration crate attempted to download and execute a payload from a remote site. The malicious crate had 1 version published on 2026-06-02, approximately 1 hour before removal, and had no evidence of actual usage. This crate had no dependencies on crates.io. Thanks to Kirill...

Potential use-after-free due to lack of panic safety in `LruCache::pop()`

LruCache::pop in lru was not panic-safe. If the Drop implementation of a stored key panics during pop, self.detach is never called, leaving dangling pointers in the internal doubly-linked list. A subsequent cache operation that triggers eviction can then dereference these dangling pointers: - The...

Denial of service in Steamworks game clients/servers using P2P authentication

Processing the raw ValidateAuthTicketResponset callback data panics when the meAuthSessionResponse field is kEAuthSessionResponseAuthTicketNetworkIdentityFailure. This can lead to denial of service in game clients and servers using the beginauthenticationsession API to authenticate players if a...

Potential out-of-bounds write via public `Context` fields

The Context struct has all fields public pub dlen, pub digest, etc.. Code from other modules within the same crate can directly modify dlen to a value exceeding the digest vector length. When reset is subsequently called, self.digestself.dlen as usize = 0 becomes an out-of-bounds write. Withdrawa...

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 —...

Unsound access to padding bytes while serializing date/time values using the Mysql backend

Diesel-async uses the mysql-async crate for interacting with Mysql compatible databases. This library already provides access to deserialized data for date/time releated types. Diesel-async then translated these deserialized data back to their serialized binary representation to hook into diesels...

Possible unaligned data access for implementations of `SqliteAggregate`

Diesel allows to register custom aggregate SQL functions for SQLite via the SqliteAggregate interface. To store an instance of the custom aggregate processor Diesel relied on the sqlite3aggregatecontext function provided by sqlite. This function doesn't provide any guarantees about alignment of t...

Symbol confusion after hasher panic in `intaglio` interners

Affected versions of this crate can leave all SymbolTable variants in an internally inconsistent state if a custom BuildHasher panics during HashMap::insert and the caller recovers with catchunwind. The intern implementations committed a vec.push... before the matching map.insert... completed. If...

CRLs not considered authoritative by Distribution Point due to faulty matching logic

If a certificate had more than one distributionPoint, then only the first distributionPoint would be considered against each CRL's IssuingDistributionPoint distributionPoint, and then the certificate's subsequent distributionPoints would be ignored. The impact was that correctly provided CRLs wou...

Denial of service in Quinn endpoints

Receiving QUIC transport parameters containing invalid values could lead to a panic. Unfortunately the maintainers did not properly assess usage of unwrap calls in the transport parameters parsing code, and we did not have sufficient fuzzing coverage to find this issue. We have since added a...

HTTP Request Smuggling via Premature Upgrade

Pingora versions prior to 0.8.0 would immediately forward bytes following a request with an Upgrade header to the backend, without waiting for a 101 Switching Protocols response. This allows an attacker to smuggle requests to the backend and bypass proxy-level security controls. This vulnerabilit...

HTTP Request Smuggling via HTTP/1.0 and Transfer-Encoding Misparsing

Pingora versions prior to 0.8.0 improperly allowed HTTP/1.0 request bodies to be close-delimited and incorrectly handled multiple Transfer-Encoding values. This allows an attacker to desync Pingora's request framing from backend servers and smuggle requests to the backend. This vulnerability...
