CVE-2025-68160 is a heap-based out-of-bounds write in OpenSSL's line-buffering BIO filter, BIO_f_linebuffer. The flaw is triggered when an application writes large data containing no newline through a BIO chain using this filter and the subsequent BIO performs a short write. Incorrect handling of the short-write condition can write beyond a heap allocation. OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1, and 1.0.2 are affected. The BIO implementation is outside the OpenSSL FIPS module boundary; consequently, OpenSSL FIPS modules are not affected.
