github-actions[bot] opened issue #13833:

Invalid pointer dereference in fmt::Pointer impl for Atomic and Shared when the underlying pointer is invalid

Details
Package	crossbeam-epoch
Version	0.9.18
URL	https://github.com/crossbeam-rs/crossbeam/pull/1276
Date	2026-07-06
Patched versions	>=0.9.20
Unaffected versions	<0.9.0

Affected versions of fmt::Display dereference the underlying pointer. This causes a invalid pointer dereference e.g., when a pointer created with Atomic::null or Shared::null. fmt::Debug impls and pre-0.9 fmt::Display impls, which do not dereference pointers, are not affected by this issue.

See advisory page for additional details.
