CVE-2026-44673 not yet assigned priority: Debian including 2 source packages (libyang, libyang2), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
libyang is a YANG data modeling language library. Prior to SO 5.2.15, lyb_read_string() in src/parser_lyb.c contains an integer overflow that results in a heap buffer overflow when parsing a maliciously crafted LYB binary blob. An attacker who can supply LYB data to any libyang consumer (NETCONF server, sysrepo, etc.) can trigger a crash or potential heap corruption. This vulnerability is fixed in SO 5.2.15.
