Finally the skb is dereferenced to bump a 'hw'\nperformance counter. This is wrong because if the completer task is\nalready running in a separate thread it may have already processed the skb\nand freed it which can cause a seg fault. This has been observed\ninfrequently in testing at high scale.\n\nThis patch fixes this by changing the order of enqueuing the packet until\nafter the counter is accessed." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "0b1e5b99a48b", "version_value": "c91fb72a2ca6" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "4.12", "status": "affected" }, { "version": "0", "lessThan": "4.12", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.285", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.227", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.168", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.93", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.33", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.12", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.3", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/c91fb72a2ca6480d8d77262eef52dc5b178463a3", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/c91fb72a2ca6480d8d77262eef52dc5b178463a3" }, { "url": "https://git.kernel.org/stable/c/de5a059e36657442b5637cc16df5163e435b9cb4", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/de5a059e36657442b5637cc16df5163e435b9cb4" }, { "url": "https://git.kernel.org/stable/c/e0e14dd35d4242340c7346aac60c7ff8fbf87ffc", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/e0e14dd35d4242340c7346aac60c7ff8fbf87ffc" }, { "url": "https://git.kernel.org/stable/c/faa8d0ecf6c9c7c2ace3ca3e552180ada6f75e19", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/faa8d0ecf6c9c7c2ace3ca3e552180ada6f75e19" }, { "url": "https://git.kernel.org/stable/c/21b4c6d4d89030fd4657a8e7c8110fd941049794", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/21b4c6d4d89030fd4657a8e7c8110fd941049794" }, { "url": "https://git.kernel.org/stable/c/bbad88f111a1829f366c189aa48e7e58e57553fc", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/bbad88f111a1829f366c189aa48e7e58e57553fc" }, { "url": "https://git.kernel.org/stable/c/30df4bef8b8e183333e9b6e9d4509d552c7da6eb", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/30df4bef8b8e183333e9b6e9d4509d552c7da6eb" }, { "url": "https://git.kernel.org/stable/c/2b23b6097303ed0ba5f4bc036a1c07b6027af5c6", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/2b23b6097303ed0ba5f4bc036a1c07b6027af5c6" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
