If\nskb allocation fails, keep on pulling packets out of the Rx DMA queue: we\nshouldn't break the polling immediately and thus falsely indicate to the\noctep_napi_poll() that the Rx pressure is going down. As there is no\nassociated skb in this case, don't process the packets and don't push them\nup the network stack - they are skipped.\n\nHelper function is implemented to unmmap/flush all the fragment buffers\nused by the dropped packet. 'alloc_failures' counter is incremented to\nmark the skb allocation error in driver statistics.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-476"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2024-50145", "ASSIGNER": "cve@kernel.org"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 1.8}}, "publishedDate": "2024-11-07T10:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.12:rc1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.12:rc2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.12:rc4:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.12:rc3:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.11.6", "versionStartIncluding": "6.7"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.6.59", "versionStartIncluding": "6.2"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.1.115", "versionStartIncluding": "5.19"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2024-11-15T19:50Z"}
