CVE-2026-41677: rust-opennssl has an Out-of-bounds read in PEM password callback when returning an oversized length
(updated )
The *_from_pem_callback APIs did not validate the length returned by the user’s callback. A password callback that returns a value larger than the buffer it was given can cause some versions of OpenSSL to over-read this buffer. OpenSSL 3.x is not affected by this.
