Non-atomic writes in cgc
Ptr
in cgc
Multiple soundness issues in Affected versions of this crate have the following issues:
-
Ptr
implementsSend
andSync
for all types, this can lead to data
races by sending non-thread safe types across threads. -
Ptr::get
violates mutable alias rules by returning multiple mutable
references to the same object. -
Ptr::write
uses non-atomic writes to the underlying pointer. This means
that when used across threads it can lead to data races.
