Wrong memory orderings violates mutual exclusion in spin

Wrong memory orderings inside the RwLock implementation allow for two writers to acquire the lock at the same time. The drop implementation used Ordering::Relaxed, which allows the compiler or CPU to reorder a mutable access on the locked data after the lock has been yielded. Only users of the...

Rust Competition Condition Problem Vulnerability

Rust is a general-purpose, compiled programming language from the Mozilla Foundation. A security vulnerability exists in Rust lockapi crate before 0.4.2, which stems from the possibility that an unsound RwLockReadGuard could lead to data contention...

Some lock_api lock guard objects can cause data races

Affected versions of lockapi had unsound implementations of the Send or Sync traits for some guard objects, namely: MappedMutexGuard MappedRwLockReadGuard MappedRwLockWriteGuard RwLockReadGuard RwLockWriteGuard These guards could allow data races through types that are not safe to Send across...

Lock order reversal between page_alloc_lock and mm_rwlock

ISSUE DESCRIPTION The locks pagealloclock and mmrwlock are not always taken in the same order. This raises the possibility of deadlock. The incorrect order occurs only in the implementation of the deprecated domctl hypercall XENDOMCTLgetmemlist. IMPACT A malicious guest administrator may be able ...
