This matches the AV:L used for the analogous device-supplied-config OOB in CVE-2024-53092.\nAC:L - The device simply advertises rss_max_key_size > 40 and the overflow is deterministic on every probe — no race, no timing window, and the attacker picks the exact overflow length and (via ethtool set_rxfh) the exact bytes written past the array.\nPR:N - The out-of-bounds write and the BUG_ON panic occur automatically inside virtnet_probe()/virtnet_init_default_rss() during driver binding, and virtnet_commit_rss_command() DMAs the out-of-bounds key bytes back to the device on link-up, all with no guest account or credentials required.\nUI:N - Device probe, hotplug, and interface bring-up are driven automatically by the driver core and normal network configuration; no victim action is needed.\nS:U - The out-of-bounds read and write are confined to the guest kernel's own heap and security authority, with no IOMMU, hypervisor, or sandbox boundary crossed by the impact itself.\nC:H - virtnet_get_rxfh() memcpy's vi->rss_key_size bytes from the 40-byte key array to userspace and virtnet_commit_rss_command() hands the same over-long buffer to the device, leaking adjacent virtnet_info heap contents including the indirection_table kernel pointer; once that pointer is overwritten via set_rxfh, get_rxfh reads back arbitrary kernel addresses.\nI:H - netdev_rss_key_fill() writes past key[] at probe and virtnet_set_rxfh()'s memcpy(vi->rss.key, rxfh->key, vi->rss_key_size) writes attacker-chosen bytes over the adjacent indirection_table pointer, after which vi->rss.indirection_table[i] = rxfh->indir[i] is an arbitrary kernel write suitable for control-flow hijacking; on 6.1/6.6 key[] is the last struct member so the overflow lands directly on subsequent virtnet_info fields.\nA:H - netdev_rss_key_fill() contains BUG_ON(len > 52), so any device advertising rss_max_key_size of 53–255 panics the guest kernel outright during probe, and the corrupted indirection_table pointer additionally trips sg_set_buf()'s virt_addr_valid BUG_ON and wild dereferences."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/virtio_net.c"],"versions":[{"version":"c7114b1249fa3b5f3a434606ba4cc89c4a27d618","lessThan":"f3401e3c8d339ddb6ccb2e3d11ad634b7846a806","status":"affected","versionType":"git"},{"version":"c7114b1249fa3b5f3a434606ba4cc89c4a27d618","lessThan":"af0aa8aecbe8985079232902894cc4cb62795691","status":"affected","versionType":"git"},{"version":"c7114b1249fa3b5f3a434606ba4cc89c4a27d618","lessThan":"6a18a783b1fa590ad1ed785907263e4b86adcfe2","status":"affected","versionType":"git"},{"version":"c7114b1249fa3b5f3a434606ba4cc89c4a27d618","lessThan":"3f7d9c1964fcd16d02a8a9d4fd6f6cb60c4cc530","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/virtio_net.c"],"versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"6.1.117","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.61","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.8","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.1.117"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.6.61"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.11.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f3401e3c8d339ddb6ccb2e3d11ad634b7846a806"},{"url":"https://git.kernel.org/stable/c/af0aa8aecbe8985079232902894cc4cb62795691"},{"url":"https://git.kernel.org/stable/c/6a18a783b1fa590ad1ed785907263e4b86adcfe2"},{"url":"https://git.kernel.org/stable/c/3f7d9c1964fcd16d02a8a9d4fd6f6cb60c4cc530"}],"title":"virtio_net: Add hash_key_length check","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.1,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"id":"CVE-2024-53082","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-10-01T20:11:57.489221Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-125","description":"CWE-125 Out-of-bounds Read"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-01T20:17:14.747Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:29:05.254Z"}}]}}
