The CAN frame modification rules allow bitwise logical operations that can be also applied to the can_dlc field. The privileged user \"root\" with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data length code a higher value than the available CAN frame data size. In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a system crash. Because of a missing check, the CAN drivers may write arbitrary content beyond the data registers in the CAN controller's I/O memory when processing can-gw manipulated outgoing frames.",null,[],[],[],[14],{"_key":15},"CVE-2019-3701",[17,19],{"_key":18},"DLA-1731-1",{"_key":20},"DLA-1771-1",[],[],"2019-01-03T16:29:00.553Z","2026-04-28T20:20:42.227006Z",{"cisa_kev":26,"cisa_ransomware":26,"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,[28],{"url":29,"sources":30,"tags":32},"https://security-tracker.debian.org/tracker/CVE-2019-3701",[31],"osv_debian",[33],"Advisory",[],[],[37],{"source":31,"cvss_v2_0":9,"cvss_v3_0":38,"cvss_v3_1":9,"cvss_v4_0":9},{"baseScore":39,"baseSeverity":9,"vectorString":40,"impactScore":41,"exploitabilityScore":42},4.4,"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H",6,2.1,[44],{"ecosystem":45,"name":46,"vendor":47,"product":46,"cpe_part":9,"purl_type":48,"purl_namespace":47,"purl_name":46,"source":9,"versions":49},"Debian","linux","debian","deb",[50,56,57,58],{"version":51,"is_range":52,"range_type":53,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":55,"fixed_in":9},"lt4_19_20_1",true,"ecosystem","4.19.20-1","excluding",{"version":51,"is_range":52,"range_type":53,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":55,"fixed_in":9},{"version":51,"is_range":52,"range_type":53,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":55,"fixed_in":9},{"version":51,"is_range":52,"range_type":53,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":55,"fixed_in":9}]
