CVE-2026-15442CVE-2026-15442
wolfssl / wolfssl
Description
In all builds that make use of (D)TLS, including default builds, there is a series of conditional states during the TLS shutdown which could lead to a heap-use-after free. If an application ended up getting a partial wolfSSL_read() which is sometimes caused by a small user buffer passed in, then called wolfSSL_shutdown for a bidirectional close and attempted to wolfSSL_read() again while the peer continues trying to send data during the shutdown it would lead to a state where a potential heap-use-after free happened.
