The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds,\n causing OOB reads and (on big-endian systems) OOB endianness flips.\n - A packet can overlap the metadata array, causing a later OOB\n endianness flip to corrupt data used by a cloned SKB that has already\n been handed off into the network stack.\n - A packet SKB can be constructed whose tail is far beyond its end,\n causing out-of-bounds heap data to be considered part of the SKB's\n data.\n\nI have tested that this can be used by a malicious USB device to send a\nbogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response\nthat contains random kernel heap data.\nIt's probably also possible to get OOB writes from this on a\nlittle-endian system somehow - maybe by triggering skb_cow() via IP\noptions processing -, but I haven't tested that." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/usb/ax88179_178a.c" ], "versions": [ { "version": "e2ca90c276e1", "lessThan": "711b6bf3fb05", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "63f0cfb36c1f", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "1668781ed24d", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "a0fd5492ee76", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "758290defe93", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "ffd0393adcdc", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "9681823f96a8", "status": "affected", "versionType": "git" }, { "version": "e2ca90c276e1", "lessThan": "57bc3d3ae8c1", "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/usb/ax88179_178a.c" ], "versions": [ { "version": "3.9", "status": "affected" }, { "version": "0", "lessThan": "3.9", "status": "unaffected", "versionType": "custom" }, { "version": "4.9.303", "lessThanOrEqual": "4.9.*", "status": "unaffected", "versionType": "custom" }, { "version": "4.14.268", "lessThanOrEqual": "4.14.*", "status": "unaffected", "versionType": "custom" }, { "version": "4.19.231", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "custom" }, { "version": "5.4.180", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "custom" }, { "version": "5.10.101", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "custom" }, { "version": "5.15.24", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "custom" }, { "version": "5.16.10", "lessThanOrEqual": "5.16.*", "status": "unaffected", "versionType": "custom" }, { "version": "5.17", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/711b6bf3fb052f0a6b5b3205d50e30c0c2980382" }, { "url": "https://git.kernel.org/stable/c/63f0cfb36c1f1964a59ce544156677601e2d8740" }, { "url": "https://git.kernel.org/stable/c/1668781ed24da43498799aa4f65714a7de201930" }, { "url": "https://git.kernel.org/stable/c/a0fd5492ee769029a636f1fb521716b022b1423d" }, { "url": "https://git.kernel.org/stable/c/758290defe93a865a2880d10c5d5abd288b64b5d" }, { "url": "https://git.kernel.org/stable/c/ffd0393adcdcefab7e131488e10dcfde5e02d6eb" }, { "url": "https://git.kernel.org/stable/c/9681823f96a811268265f35307072ad80713c274" }, { "url": "https://git.kernel.org/stable/c/57bc3d3ae8c14df3ceb4e17d26ddf9eeab304581" } ], "title": "net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup", "x_generator": { "engine": "bippy-c9c4e1df01b2" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-03T15:25:01.769Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/711b6bf3fb052f0a6b5b3205d50e30c0c2980382", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/63f0cfb36c1f1964a59ce544156677601e2d8740", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/1668781ed24da43498799aa4f65714a7de201930", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/a0fd5492ee769029a636f1fb521716b022b1423d", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/758290defe93a865a2880d10c5d5abd288b64b5d", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ffd0393adcdcefab7e131488e10dcfde5e02d6eb", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/9681823f96a811268265f35307072ad80713c274", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/57bc3d3ae8c14df3ceb4e17d26ddf9eeab304581", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2022-48805", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T16:58:50.903350Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:34:13.907Z" } } ] } }
