CVE-2026-49760

CVE-2026-49760

Description

Stack-based Buffer Overflow vulnerability in Erlang OTP (erl_interface) allows Stack-based Buffer Overflow.

This vulnerability is associated with program file lib/erl_interface/src/misc/ei_printterm.c and program routine ei_s_print_term.

The C function ei_s_print_term uses an internal 2000-character stack buffer to format terms. When called with an encoded Erlang term containing a very large integer (encoded representation exceeding 2000 characters), the buffer overflows. The overflow bytes are restricted to the ASCII values of 0-9 and A-F, which limits exploitation to Denial of Service.

The companion function ei_print_term, which prints directly to a FILE instead of a memory buffer, does not contain this bug.

This issue affects OTP from OTP 17.0 before 27.3.4.13, 28.5.0.2 and 29.0.2, corresponding to erl_interface from 3.7.16 before 5.5.2.1, 5.7.0.1 and 5.8.1.
