The subsequent get_len() call then dereferences *bs->cur++, reading 1 byte past the end of the buffer.  If that byte has bit 7 set, get_len() reads a second byte as well.  This can be triggered remotely by sending a crafted Q.931 SETUP message with a User-User Information Element containing exactly 2 bytes of PER-encoded data ({0x08, 0x00}) to port 1720 through a firewall with the nf_conntrack_h323 helper active.  The decoder fully consumes the PER buffer before reaching this code path, resulting in a 1-2 byte heap-buffer-overflow read confirmed by AddressSanitizer.  Fix this by checking for 2 bytes (the maximum that get_len() may read) instead of the uninitialized `len`.  This matches the pattern used at every other get_len() call site in the same file, where the caller checks for 2 bytes of available data before calling get_len().",null,[],[],[],[14],{"_key":15},"CVE-2026-43233",[],[],[],"2026-05-06T12:16:43.417Z","2026-06-15T19:06:25.950487005Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2026-43233",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},8.2,"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H",7,10,[40],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,50,54,57,60],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":51,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":52,"version_end_type":53,"fixed_in":9},"lt5_10_257_1","5.10.257-1","excluding",{"version":55,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":56,"version_end_type":53,"fixed_in":9},"lt6_1_170_1","6.1.170-1",{"version":58,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":59,"version_end_type":53,"fixed_in":9},"lt6_12_85_1","6.12.85-1",{"version":61,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":62,"version_end_type":53,"fixed_in":9},"lt6_19_6_1","6.19.6-1"]
