This is a problem, however, as there's a gap\nbetween the two phases in which a packet may come into rxrpc_encap_rcv()\nfrom the UDP packet but we oops when trying to wake the not-yet created I/O\nthread.\n\nAs a quick fix, just make rxrpc_encap_rcv() discard the packet if there's\nno I/O thread yet.\n\nA better, but more intrusive fix would perhaps be to rearrange things such\nthat the socket creation is done by the I/O thread." } ] }, "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": "a275da62e8c1", "version_value": "cdf4bbbdb956" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "6.2", "status": "affected" }, { "version": "0", "lessThan": "6.2", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.55", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.14", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.3", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/cdf4bbbdb956d7426f687f38757ebca2a2759a0f", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/cdf4bbbdb956d7426f687f38757ebca2a2759a0f" }, { "url": "https://git.kernel.org/stable/c/56e415202b8a17de6496f4023e545fcb66f118ec", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/56e415202b8a17de6496f4023e545fcb66f118ec" }, { "url": "https://git.kernel.org/stable/c/c64f5fc95e9612fdf75587c8e21e494e614c18e2", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/c64f5fc95e9612fdf75587c8e21e494e614c18e2" }, { "url": "https://git.kernel.org/stable/c/bc212465326e8587325f520a052346f0b57360e6", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/bc212465326e8587325f520a052346f0b57360e6" } ] }, "generator": { "engine": "bippy-8e903de6a542" } }
