CVE-2026-6654

A flaw was found in the `thin_vec` component of `mozilla/thin-vec`. This vulnerability involves a memory management error known as a Double-Free/Use-After-Free (UAF), which occurs in the `IntoIter::drop` and `ThinVec::clear` functions. When a specific error condition (a panic in `ptr::drop_in_place`) is triggered, the system fails to correctly manage memory, potentially allowing an attacker to execute malicious code or cause the application to crash, leading to a denial of service.
