    Mimalloc Can Allocate Memory with Bad Alignment

    GHSA-g23h-7vf9-xc25

    Affected
    • crates.io mimalloc < 0.1.39
    Fixed in
    0.1.39· Vendor fix available
    Issue
    This crate depended on a promise regarding alignments made by the author of the mimalloc allocator to avoid using aligned allocation functions where possible for performance reasons. Since then, the mimalloc allocator's logic changed, making it break this promise. This caused this crate to return memory with an incorrect alignment for some allocations, particularly those with large alignments. The flaw was fixed by always using the aligned allocation functions.

    Recommended action: Upgrade to 0.1.39 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
