The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality."}, {"lang": "es", "value": "Se encontr\u00f3 una falla en el subsistema Netfilter en el kernel de Linux. El problema est\u00e1 en la funci\u00f3n nft_byteorder_eval(), donde el c\u00f3digo itera a trav\u00e9s de un bucle y escribe en la matriz `dst`. En cada iteraci\u00f3n, se escriben 8 bytes, pero `dst` es una matriz de u32, por lo que cada elemento solo tiene espacio para 4 bytes. Eso significa que cada iteraci\u00f3n sobrescribe parte del elemento anterior, lo que posiblemente lleve a una escritura fuera de los l\u00edmites. Esta falla permite que un usuario local provoque una denegaci\u00f3n de servicio o potencialmente aumente sus privilegios en el sistema."}], "lastModified": "2026-10-16T15:16:08.413", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "07B237A9-69A3-4A9C-9DA0-4E06BD37AE73"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "24DFB8C6-5FA0-4F09-BFF5-391E59AE9F03", "versionEndExcluding": "6.6.3"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:fedoraproject:fedora:39:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B8EDB836-4E6A-4B71-B9B2-AA3E03E0F646"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F4CFF558-3C47-480D-A2F0-BABF26042943"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7F6FB57C-2BC7-487C-96DD-132683AEB35D"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
