{"schema":"threatline.record/2","record":{"id":"CVE-2026-98375","aliases":[],"summary":"xen/netfront: drop RX packets with a short Ethernet header","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxen/netfront: drop RX packets with a short Ethernet header\n\nhandle_incoming_queue() pulls pull_to bytes into the head before\ncalling eth_type_trans().  pull_to is the length of the first RX slot,\ncapped at RX_COPY_THRESHOLD, and that length comes from the backend.\nNothing checks it against ETH_HLEN.\n\nIf the first slot is shorter than ETH_HLEN and more slots follow, the\nhead ends up shorter than an Ethernet header while skb->len is longer,\nand eth_type_trans() BUG()s in __skb_pull().  If the whole packet is\nshorter than ETH_HLEN, eth_type_trans() reads the header past the end\nof the data instead.\n\nPull at least ETH_HLEN, and drop the packet if that fails, which also\ndrops packets too short to hold an Ethernet header.  This also checks\nthe return value of the pull, which was ignored.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"0d160211965b79de989cf2d170985abeb8da5ec6","lessThan":"0542d213253eec18785a24b603b28bd385dfe4a5","status":"affected","versionType":"git"},{"version":"0d160211965b79de989cf2d170985abeb8da5ec6","lessThan":"236a17caebcff31f75bec5ff4136bde2de944e40","status":"affected","versionType":"git"},{"version":"0d160211965b79de989cf2d170985abeb8da5ec6","lessThan":"72d2f54367895d6e236b9857892e2e6b6036e067","status":"affected","versionType":"git"},{"version":"0d160211965b79de989cf2d170985abeb8da5ec6","lessThan":"e2b721bc30f40ffa7ccc36a56d4e8990b8c0538e","status":"affected","versionType":"git"},{"version":"0d160211965b79de989cf2d170985abeb8da5ec6","lessThan":"089e58805c452e52179482b1025a8e309a57f801","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.23","status":"affected"},{"version":"0","lessThan":"2.6.23","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"0542d213253eec18785a24b603b28bd385dfe4a5","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"236a17caebcff31f75bec5ff4136bde2de944e40","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"72d2f54367895d6e236b9857892e2e6b6036e067","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","source_modified_at":"2026-10-21T12:54:59.248Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"089e58805c452e52179482b1025a8e309a57f801","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00176,"percentile":0.06798,"score_date":"2026-10-23"},"published_at":"2026-10-09T07:10:45.930Z","modified_at":"2026-10-21T12:54:59.248Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98375","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:54:59.248Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98375","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/0542d213253eec18785a24b603b28bd385dfe4a5"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/236a17caebcff31f75bec5ff4136bde2de944e40"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/72d2f54367895d6e236b9857892e2e6b6036e067"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e2b721bc30f40ffa7ccc36a56d4e8990b8c0538e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/089e58805c452e52179482b1025a8e309a57f801"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:54:59.248Z","content_hash":"47843078097d57d62904c8e53f86b84413d902ff8dc1fa4438b434487149f784"}}
