CVE-2026-41681

8.1 highEPSS 0.4%

High (8.1) in rust-openssl project rust-openssl. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in openssl 0.10.78.

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVP_DigestFinal() always writes EVP_MD_CTX_size(ctx) to the out buffer. If out is smaller than that, MdCtxRef::digest_final() writes past its end, usually corrupting the stack. This is reachable from safe Rust. This vulnerability is fixed in 0.10.78.
