CVE-2026-104594 Details
Description
libosmocore through 1.14.1 contains out-of-bounds reads in the IPA CCM identity-tag parsers in src/gsm/ipa.c. This allows a remote attacker to obtain sensitive information.
A heap-based out-of-bounds read vulnerability has been identified in libosmocore versions through 1.14.1. The issue resides in the IPA CCM identity-tag parsers within the file src/gsm/ipa.c. This vulnerability allows remote attackers to read beyond the allocated buffer, potentially leading to the disclosure of sensitive information. The problem arises from improper handling of TLV (Tag-Length-Value) structures, where the length field is not correctly validated before being used, enabling exploitation through crafted inputs.
Users can upgrade to libosmocore version 1.14.2, where this vulnerability has been fixed.
