CVE-2026-92842 is a medium severity heap-based buffer overflow vulnerability in PHP related to the convert.base64-encode, convert.quoted-printable-encode, and convert.quoted-printable-decode stream filters. The issue arises because the filters accept a line-break-chars option whose length is tracked separately from the string itself. The filter constructors duplicate the value using pestrdup(), which stops at the first NUL byte but retains the original length. This leads to reading past the allocated buffer when emitting a line break, causing adjacent heap memory to be copied into the output.
