Keys::next uses ptr::read to move out the Option by value, which drops the contained V when V is non-Copy e.g. String. This leaves a dangling value in the map's storage slot. Subsequent get operations on that key return a dangling reference to already-freed memory. This can be triggered through...

Chomp::inner uses std::ptr::read unaligned to move out the value from a raw pointer. If the original value is an owned type e.g. Box, calling inner moves out the ownership, but the original variable will still be dropped at the end of its scope. This causes the same heap memory to be freed twice,...

GHSA-3QM2-RFQW-FMRW move_elements can double-free objects on panic

Affected versions of scratchpad used ptr::read to read elements while calling a user provided function f on them. Since the pointer read duplicates ownership, a panic inside the user provided f function could cause a double free when unwinding. The flaw was fixed in commit 891561bea by removing t...

RUSTSEC-2021-0009 panic safety issue in `impl TransformContent<S, D> for [S; (2|3|4)]`

Affected versions of this crate did not guard against double drop while temporarily duplicating objects' ownership using ptr::read. Upon panic in a user-provided function conversion, objects that are copied by ptr::read are dropped twice, leading to memory corruption. The flaw was corrected in...
