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.\n\nThe companion function ei_print_term, which prints directly to a FILE instead of a memory buffer, does not contain this bug.\n\nThis issue affects OTP from OTP 17.0 before OTP 27.3.4.13, OTP 28.5.0.2, and OTP 29.0.2, corresponding to erl_interface from 3.7.16 before 5.5.2.1, 5.7.0.1, and 5.8.1. Whether OTP before OTP 17.0, corresponding to erl_interface before 3.7.16, is affected is unknown.","published_at":"2026-06-10T14:35:36.804000Z","last_modified_at":"2026-09-24T21:17:15.130000Z","cvss_v3_score":5.5,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":6.9,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-121"],"nvd_references":["https://github.com/erlang/otp/security/advisories/GHSA-xcxj-5pg2-v72j","https://cna.erlef.org/cves/CVE-2026-49760.html","https://osv.dev/vulnerability/EEF-CVE-2026-49760","https://www.erlang.org/doc/system/versions.html#order-of-versions","https://github.com/erlang/otp/commit/0bef277b2d39dc8babb9ceb4f5d0a456f3007111"],"vuln_status":"Modified","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-09-26T05:38:24.218835Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
